Prosecutors allege Quincy Dean Norton Sr., 36, murdered his 31-year-old wife, Tamika Norton, with his children in the next room at their home on Mira Vista Court on July 22, 2006.
Norton's retrial, which began in late August, has included testimony from his two sons and former sister-in-law, who recounted Norton's alleged history of domestic violence against Tamika Norton.
This morning, prosecutor Al Giannini recounted the boys' testimony to a packed courtroom in his closing argument, saying that they heard their mother scream the morning she was murdered, they heard banging noises, and that the defendant was the only person in the room with her.
"It is unwavering, it is uncontradicted, and it is the truth," Giannini said of the boys' accounts.
Defense attorney Lisa Maguire, whose closing argument is scheduled to begin this afternoon, has argued that Norton's girlfriend, Anitra Johnson, was the killer.
Giannini said this morning that Johnson had no motive to kill Tamika Norton, since the victim had intended to divorce the defendant.
Norton's first trial ended with his conviction on May 15, 2008, when a jury found him guilty of first-degree murder.
The conviction was later overturned when Judge Craig Parsons found that Norton's attorney had provided inadequate representation.
Norton evaded police for more than a month while being sought for questioning after the murder. Police arrested him in San Jose on Aug. 27, 2006, when the woman whose home he was staying at told him to leave. Police arrested him as he sat at a bus stop.
Norton remains in custody without bail.
