Defensa de Murder en Texas — Texas marco completo

Tres modalidades de murder bajo sección 19.02(b)

Penal Code sección 19.02(b) tipifica murder bajo tres modalidades alternativas:

Modalidad (b)(1) — Intentional or knowing killing

Una persona comete murder si intentionally or knowingly causes the death of an individual. Esta es la modalidad clasica de murder — el acusado debe haber tenido conscious objective to cause death (intentional) o haber sido aware that death was reasonably certain (knowing) bajo Penal Code sección 6.03(a)-(b).

Modalidad (b)(2) — Intent to cause serious bodily injury

Una persona comete murder si intends to cause serious bodily injury and commits an act clearly dangerous to human life that causes the death of an individual. Esta modalidad cubre casos donde el acusado no tenía intent to kill pero tenía intent to cause serious bodily injury con un acto que era clearly dangerous to human life. Frecuentemente aplica a brutal beatings, attacks with deadly weapons not specifically aimed to kill, severely dangerous physical attacks. Lawson v. State, 64 S.W.3d 396 (Tex. Crim. App. 2001), addresses "clearly dangerous to human life" standard — objective evaluation of conduct.

Modalidad (b)(3) — Felony murder

Una persona comete murder si commits or attempts to commit a felony, other than manslaughter, and in the course and in furtherance of the commission or attempt, or in immediate flight from the commission or attempt, he commits or attempts to commit an act clearly dangerous to human life that causes the death of an individual. Esta es la felony-murder rule — provides liability for murder when death occurs during felony, even without specific intent to kill.

Felony-murder rule alcance:

• El predicate felony debe ser otro que manslaughter — manslaughter cannot bootstrap up to murder.
• Death must occur during course or furtherance of felony, or in immediate flight.
• Defendant must commit clearly dangerous act causing death.
• Mental state for the dangerous act may be reckless or even negligent — no specific intent to kill required.

Common felony-murder scenarios: deaths during aggravated robbery, burglary, arson, drug delivery, kidnapping. Even co-defendant's death (escape attempt, accident during felony) can trigger felony murder for surviving defendants.

All three modalidades carry same grade — primer grado de felonía bajo subsección (c). Sentence range: 5-99 years or life TDCJ, fine up to $10,000.

Sudden passion mitigation bajo sección 19.02(d)

Penal Code sección 19.02(d) provides a punishment-phase mitigation: "At the punishment stage of a trial, the defendant may raise the issue as to whether he caused the death under the immediate influence of sudden passion arising from an adequate cause. If the defendant proves the issue in the affirmative by a preponderance of the evidence, the offense is a felony of the second degree."

Key concepts:

• Sudden passion. Defined in sub (a)(2) as "passion directly caused by and arising out of provocation by the individual killed or another acting with the person killed which passion arises at the time of the offense and is not solely the result of former provocation."
• Adequate cause. Defined in sub (a)(1) as "cause that would commonly produce a degree of anger, rage, resentment, or terror in a person of ordinary temper, sufficient to render the mind incapable of cool reflection."
• Burden shift. Defendant must prove sudden passion by preponderance of the evidence — easier than reasonable doubt but still defendant's burden.
• Punishment-phase only. Sudden passion is NOT defense to guilt — it is mitigation determined after guilt finding. Defendant first must be convicted of murder, then sudden passion may reduce grade to second-degree felony.
• Effect of reduction. Second-degree felony (sec. 12.33): 2-20 years TDCJ, fine $10,000. Dramatic reduction from murder's 5-99 years or life range.

Common sudden-passion scenarios: discovering spouse in act of adultery, response to serious provocation (severe insult plus physical aggression), discovery of crime against family member, mutual combat scenarios escalating beyond control. Words alone are typically insufficient for "adequate cause" — must involve provocation that ordinary person would find insufferable.

Casos importantes: McKinney v. State, 179 S.W.3d 565 (Tex. Crim. App. 2005), addresses sudden passion requirements. Trevino v. State, 100 S.W.3d 232 (Tex. Crim. App. 2003), addresses provocation standard.

Sudden passion strategy: defense investigates relationship history between defendant and victim, immediate circumstances leading to killing, defendant's mental state, witness observations of defendant's emotional state. Expert testimony from mental health professionals may support the claim.

Felony-murder rule in depth

The felony-murder rule bajo sec. 19.02(b)(3) is one of the broadest grounds for murder liability. Detailed analysis:

Predicate felony requirements

• Must be felony (any grade — state jail, third, second, first, capital).
• Cannot be manslaughter — that would bootstrap manslaughter into murder, defeating the legislative grade distinctions.
• Common predicates: aggravated robbery, robbery, burglary, aggravated burglary, arson, drug delivery, kidnapping, aggravated kidnapping, aggravated sexual assault, sexual assault, evading arrest with deadly weapon.
• Defense attacks predicate felony — if predicate cannot be proven beyond reasonable doubt, felony murder fails entirely.

"In course of or in furtherance of"

Death must occur during commission, attempted commission, or in immediate flight from the felony. Includes:

• During the felony itself (e.g., shot fired during robbery).
• Attempted commission (felony interrupted but death occurs).
• Immediate flight — escape from scene, pursuit by victim or police, return to safe location.

Defense attacks: was death really "in course of" felony, or in a separate transaction? Was the flight still "immediate" at time of death, or had defendant reached safety? Was death related to the felony or independent?

"Clearly dangerous to human life"

The act causing death must be objectively dangerous. Bajo Lawson v. State, 64 S.W.3d 396 (Tex. Crim. App. 2001), evaluation is objective — from perspective of reasonable person observing the act. Acts firing weapons in populated áreas, deliberate vehicular impact, severe physical attacks generally qualify. Less obviously dangerous acts (e.g., shoving someone) may not qualify even if death unexpectedly results.

Co-defendant liability

Under felony-murder rule, all participants in predicate felony can be liable for death caused during felony, even if they did not personally cause death. Texas Penal Code sec. 7.02 (party liability) extends liability to those who solicit, encourage, direct, aid, or attempt to aid commission of felony. Defense for non-shooter co-defendants attacks: (a) whether co-defendant's participation rose to party liability level; (b) whether co-defendant could have anticipated death; (c) Enmund v. Florida, 458 U.S. 782 (1982), and Tison v. Arizona, 481 U.S. 137 (1987), limit death penalty for non-killers — also relevant in murder cases.

Self-defense and Justification under Capítulo 9

Self-defense bajo Penal Code Capítulo 9 is the most frequently raised defense to murder charges. Key provisions:

• Sec. 9.32 (deadly force in defense of person). Justified using deadly force when (1) non-deadly force would be justified under sec. 9.31, AND (2) reasonably believes deadly force is immediately necessary to protect against unlawful deadly force, OR to prevent imminent commission of aggravated kidnapping, murder, sexual assault, aggravated sexual assault, robbery, or aggravated robbery.
• Sec. 9.31 (self-defense, non-deadly force). Justified using force when reasonably believes immediately necessary to protect against unlawful force.
• Castle Doctrine bajo sec. 9.32(b). Presumption of reasonableness if person against whom force used was unlawfully entering vivienda, vehículo, or lugar de empleo, or was committing or attempting aggravated kidnapping, murder, sexual assault, aggravated sexual assault, robbery, or aggravated robbery. Presumption is rebuttable.
• Sec. 9.33 (defense of third person). Justified using force/deadly force to protect third person if one could reasonably act under sec. 9.31/9.32 to protect self.
• Sec. 9.42 (deadly force to protect property). Limited application — generally only nighttime, only to prevent arson, burglary, robbery, theft during nighttime, or criminal mischief during nighttime, only if property cannot be protected or recovered by other means.
• Sec. 9.22 (necessity). Conduct justified if reasonable belief immediately necessary to avoid imminent harm and harm avoided greater than harm caused.

Self-defense limitations bajo sec. 9.31(b): not available if defendant: (a) provoked use of unlawful force by other; (b) verbally provoked the encounter; (c) sought encounter knowing use of force would result; (d) is engaged in aggravated robbery, aggravated kidnapping, murder, sexual assault, or aggravated sexual assault.

Carga de prueba: defendant produces evidence supporting self-defense (any evidence including own testimony); state disproves beyond reasonable doubt. Ferrel v. State, 55 S.W.3d 586 (Tex. Crim. App. 2001). Jury must be instructed if any supporting evidence exists.

Defense investigation in self-defense murder cases: prior history between defendant and victim (history of violence, threats, prior assaults), sequence of immediate events, evidence of unlawful aggression by victim (weapons, threats, physical attack), defendant's reasonable belief, location and circumstances, witness corroboration, surveillance video.

Suppression motions and constitutional defenses

Pretrial suppression motions are central in murder defense:

• Fourth Amendment suppression. Evidence derived from illegal search or seizure suppressible bajo CCP Art. 38.23. Murder investigations frequently involve searches of vehicles, residences, computers, cell phones, vehicles, workplaces. Riley v. California, 573 U.S. 373 (2014), requires warrant for cell phone searches. Carpenter v. United States, 138 S. Ct. 2206 (2018), requires warrant for cell-site location information. Arizona v. Gant, 556 U.S. 332 (2009), limits search incident to arrest of vehicles.
• Miranda suppression. Statements obtained without Miranda warnings while in custody and under interrogation suppressible. Berkemer v. McCarty, 468 U.S. 420 (1984). Missouri v. Seibert, 542 U.S. 600 (2004), addresses question-first techniques.
• Confession suppression bajo CCP Art. 38.22. Texas has additional requirements for written and oral confessions — warnings written, recording, signatures. Failure to comply requires suppression.
• Voluntary statement bajo CCP Art. 38.21. Statements obtained by coercion, threats, or promises are inadmissible.
• Identification suppression bajo Wade/Stovall. Unduly suggestive identification procedures result in suppression. Neil v. Biggers, 409 U.S. 188 (1972), establishes reliability factors.
• Confrontation Clause bajo Crawford. Testimonial hearsay inadmissible without confrontation opportunity. Crawford v. Washington, 541 U.S. 36 (2004); Davis v. Washington, 547 U.S. 813 (2006).
• Brady violations. Prosecution must disclose favorable evidence. Brady v. Maryland, 373 U.S. 83 (1963). Common in murder cases: prior inconsistent statements by witnesses, witness criminal histories, alternative suspects investigated, exculpatory forensic evidence.
• Speedy trial. Sixth Amendment and Texas Speedy Trial Act provide protection. Barker v. Wingo, 407 U.S. 514 (1972), establishes balancing test.

Defenses — alibi, identification, causation, mens rea

Beyond self-defense and suppression, additional defenses:

• Alibi. Defendant was elsewhere at time of killing. Alibi established through: cell tower records, GPS data, surveillance video from other locations, payment records (ATM, credit card timestamps), eyewitnesses.
• Identification. Defendant is not the person who committed killing. Eyewitness identification is unreliable — over 70% of wrongful convictions later proven by DNA involved eyewitness misidentification. Defense: eyewitness experts, suppression of suggestive procedures, cross-examination on reliability factors, alternative suspects.
• DNA exclusión. DNA at scene does not match defendant. DNA matching that of unknown person not defendant.
• Failure of causation. Defendant's conduct did not cause death. Bajo Penal Code sec. 6.04, but-for and proximate causation required. Intervening medical errors, victim conduct, third party actions may break causal chain.
• Failure of mens rea. Defendant lacked required mental state. For (b)(1), defendant did not act intentionally or knowingly with respect to death. For (b)(2), defendant did not intend serious bodily injury or did not commit clearly dangerous act. For (b)(3), defendant did not participate in predicate felony, or death was not in course/furtherance.
• Lesser-included offenses. Manslaughter (sec. 19.04), criminally negligent homicide (sec. 19.05), aggravated assault (sec. 22.02). Defense frequently requests lesser-included instructions when evidence supports lesser mens rea.
• Insanity bajo sec. 8.01. Affirmative defense — defendant must prove by preponderance that at time of conduct, as a result of severe mental disease or defect, did not know conduct was wrong. Very high burden, rarely successful.
• Mental incapacity bajo sec. 8.02. Mistake of fact negating mens rea.
• Duress bajo sec. 8.05. Affirmative defense if defendant acted because compelled by threat of imminent death or serious bodily injury. Not available to capital offenses bajo sub (c) but available to other felonies.
• Mitigation evidence. Even when guilt is established, mitigation can affect sentence range — background, mental health, childhood trauma, military service, expressions of remorse, restitution efforts.

3g-listed status, parole, and sentencing strategy

Murder is 3g-listed bajo CCP Art. 42A.054. Consequences:

• Judge-imposed community supervisión restricted. Not available for sentences over 10 years. Practically unavailable in murder cases given mandatory minimum of 5 years.
• Jury-recommended community supervisión possible but rare. Bajo CCP Art. 42A.056, defendant can apply to jury for probation. Jury must specifically recommend. Defendant cannot have prior felonies. For murder, jury-recommended probation is extraordinarily rare.
• Deadly-weapon finding implications. If found, Government Code sec. 508.145(d) requires calendar time real (without good-conduct credit) equal to half of sentence or 30 years, whichever is less, but never less than 2 years. For 30-year murder sentence with deadly weapon: 15 years calendar parole eligibility. For 60-year sentence: 30 years. For life sentence: 30 years calendar.
• Federal firearms prohibition. 18 U.S.C. 922(g)(1) — vitalicia prohibition.
• Immigration consequences. Aggravated felony designation triggers virtually mandatory deportation.

Sudden passion mitigation strategy

If sudden passion can be established at punishment phase, grade reduces to second-degree felony (2-20 years). This is dramatic mitigation — from 5-99 years/life to 2-20 years. Defense develops evidence of adequate cause, defendant's emotional state, immediate provocation, mental state at time of killing.

Punishment phase strategy

Even without sudden passion, defense develops mitigation for punishment phase: family ties, employment, education, military service, lack of prior criminal history, mental health factors, remorse, restitution. Sentencing range allows substantial discretion (5-99 or life) — effective punishment-phase advocacy can substantially reduce sentence.

Plea bargaining

Common reductions: (a) murder reduced to manslaughter (second-degree, 2-20 years); (b) murder reduced to criminally negligent homicide (state jail, 180 days-2 years); (c) plea to murder with sentence cap; (d) plea to murder with stipulation against deadly-weapon finding (where evidence allows); (e) plea to lesser-included offense as part of comprehensive resolution.
