RIVERSIDE (CNS) - Jury deliberations ended today without a verdict in the trial of a parolee accused of fatally stabbing his girlfriend during an argument that ensued after she returned home late to her Moreno Valley apartment.

Brandon Ramsey Wilson, 28, faces 50 years to life in prison if convicted of first-degree murder and a sentence-enhancing weapons allegation in the March 27, 2011, slaying of Renisha Leshay Bruins.

The six-man, six-woman panel weighing Wilson's fate were sent home after three hours of deliberations because of a scheduling conflict involving one of the jurors. Deliberations were scheduled to resume at 9 a.m. Tuesdsay. Deliberations got under way last Wednesday afternoon, but the jury was given Thursday off, returning for a full day of work Friday, during which Riverside County Superior Court Judge Richard Fields admonished a juror when evidence of possible misconduct came to light. The juror was not removed from the panel, however.

In her closing argument, Deputy District Attorney Alma Hernandez described Wilson as a "cold-blooded murderer" and asked the jury to find him guilty of first-degree murder, not voluntary manslaughter, which is what the defense argued was justified.

"The defense would like you to believe that these were just random stab wounds inflicted on the victim," Hernandez said. "But how is it she got stabbed in the back and the neck? The last moments of this girl's life were violent and painful. She died looking into his eyes. And he didn't care."

According to the prosecution, Wilson attacked Bruins after she returned home in the predawn hours of March 27, 2011.

An argument followed, during which Wilson pulled a knife and stabbed the victim repeatedly, the prosecution alleges. The defendant, who had been living at the residence while working one day a week as a parking lot attendant, fled the location and, after consulting his parents, surrendered at the Moreno Valley sheriff's station, telling deputies he had accidentally killed his girlfriend, witnesses testified.

Deputy Public Defender Judith Gweon presented evidence during the five- day trial that Wilson suffered from a psychological disorder that caused him to act impulsively without realizing the consequences of his actions.

"He is generally non-confrontational, passive and shy," Gweon told the jury, adding that her client was "provoked" by Bruins, who was the first to go for a knife as the two argued.

"He went off. He overreacted," Gweon said. "The evidence shows he loved Renisha, tended to her, catered to her. Where is the motive for him to kill her?"

Hernandez blasted the proposition that Wilson was non-violent and suffered from a cognitive dysfunction, noting that he had a prior conviction for robbery and had never experienced anything that would have caused psychological trauma.

"He never even played football so he could claim a brain injury," the prosecutor said. "Being impulsive doesn't give you a pass. You can't say, 'I have a bad temper so I get to kill my girlfriend.' You need to let him know that what he did to this woman was wrong. You can do that by finding him guilty of murder."
