BUFFALO, NY (WKBW) - The jury of six men and six women will begin deliberations Wednesday morning in the trial of Luke Wright.
Wright, 32, is charged with rape, incest, sodomy and assault. He is accused of sexually assaulting and torturing his developmentally disabled younger sister before she was killed by their mother.
Laura Cummings, 23, was found dead in the family's Sherman Ave. apartment in North Collins on Jan. 21, 2010.
Eva Cummings, 51, is serving a 52-years-to-life prison term.
Closing arguments in the case were held Tuesday afternoon before Erie County Court Judge Michael D'Amico.
"Luke Wright didn't transform into a devil in the last month or two of his life," defense attorney John Nuchereno told the jury.
"You didn't hear a lifetime of bad by this young man," he said. "To the contrary. You don't turn into this kind of an evil wicked person. It doesn't happen."
"The devil lived in that house," Nuchereno said. "The devil is Eva Cummings. That was her home. A woman not fit to ever be called mother. Not for a minute."
Eva Cummings had sex with her son, according to testimony. She also had sex with multiple men in front of her children, who all committed various forms of incest.
Nuchereno told the jury that Wright, who is mildly mentally retarded, did not make a knowing and intelligent waiving of his rights before police interviewed him on several occasions.
Three police detectives testified that Wright confessed to raping and torturing his sister.
"The truth, is that this defendant's actions, this defendant's words made Laura Cummings a tortured prisoner in her own home," prosecutor Thomas Finnerty said during his closing statement.
"It is his choices, his actions which brought this defenseless, vulnerable, utterly innocent young woman to the verge of death," he said.
"The defendant's guilt has been proven by a mountain of evidence," said Finnerty.
The jury will begin deliberations after receiving instructions from the judge on Wednesday morning.
