Kenneth Foster v. the State of Texas, 06-24-00214-CR

Kenneth Foster, already incarcerated for capital murder, was convicted by a Bowie County jury of capital murder for stabbing fellow inmate Anthony Dominguez to death in the Telford Unit.
Surveillance video shows Foster walking to Dominguez’s cell, engaging in a struggle at the doorway, making a stabbing motion, and returning to the dayroom; Dominguez died minutes later from a single puncture wound to the chest.
A metal shank later recovered from a first-floor shower vent matched the puncture wound; Foster later acknowledged using a metal shank and admitted hiding the weapon.
Foster claimed he acted in self-defense (deadly-force) and out of necessity, asserting Dominguez had attacked him first and had a weapon; his statements were contradicted by other testimony and by his post-incident conduct.
The jury rejected Foster’s defensive theories and sentenced him to life without parole; Foster appealed, arguing the evidence was legally insufficient to disprove his self-defense and necessity defenses.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency to disprove deadly-force self-defense	State: Viewing all evidence favorably to prosecution, a rational jury could find Foster knowingly caused death and reject self-defense beyond a reasonable doubt	Foster: He produced evidence (his statement and testimony) that Dominguez attacked him first and he reasonably believed deadly force was immediately necessary	Court: Affirmed — evidence (video, admissions, circumstantial post-event conduct, conflicting witness accounts) supports jury’s rejection of self-defense
Sufficiency to disprove necessity defense	State: Same standard; necessity requires imminent specific harm and Foster failed to show it	Foster: Necessity (emergency/avoid imminent harm) overlaps with self-defense and should also have been established	Court: Affirmed — jury could reasonably reject necessity for same reasons it rejected deadly-force self-defense
