A San Mateo County Superior Court judge today sentenced Quincy Dean Norton Sr. to 26 years to life in state prison for stabbing his wife to death at the couple’s home more than four years ago. During an emotional sentencing this morning, Judge Craig Parsons heard statements from family and friends of the victim, Tamika Mack Norton, 31, who was stabbed by her husband in her bedroom on July 22, 2006. Their two sons, 7 and 9 years old at the time of the murder, were at home the morning their mother was slain.

David Bagby, a close friend of the victim’s family, shook while making his statement to the court, for which he apologized. Bagby asked the judge to impose the “maximum possible sentence” on “that monster that took away their loved one.”  “We know a survivor’s pain will never end,” he said. The victim’s older sister, Nicole Mannus, said the post-traumatic stress she experienced after the murder prevented her from being able to return to work for four years. She struggled to read her statement aloud and was comforted by prosecutor Al Giannini, who stood at her side and put his hand on her shoulder.

“I live with a cloud over my life,” Mannus said. “All I can think is what a sick pathetic monster (Norton) is.” Kenaya Mack, another sister who said Tamika “had a heart as big as the world,” called Norton, now 36, an “extremely violent career criminal” who changed her life forever. “I suffer from denial thinking she is going to come back,” Kenaya said. Norton sat motionless and stared straight ahead until Tamika’s mother Charene Mack advanced to address the court, when he nervously glanced over and squirmed out of his orange jail slippers.

“I don’t even know how to begin to pin the impact this crime has had upon my life,” she said. “I should have protected her,” Mack said. “I should have helped her escape an abusive relationship.” Speaking on his own behalf, Norton briefly addressed the judge. “I feel sorry for the Mack family,” Norton said. “I’m innocent of this crime.” Norton was arrested on Aug. 27, 2006, after evading police for a month.

His first trial ended with a conviction in May 2008, when a jury found him guilty of first-degree murder. The conviction was later overturned when Parsons found that Norton’s attorney had provided inadequate representation. Norton’s second trial ended Oct. 7 when he was again convicted of first-degree murder. On Nov. 9, Norton again claimed inadequate representation from his current defense attorney, Lisa Maguire, and requested a new attorney. His request was denied by Judge John Grandsaert.

This morning, before issuing the maximum sentence allowable under the law – 25 years to life plus an additional year for the use of a weapon to commit murder – Judge Parsons said the jury’s verdict was “fair and just” and that the crime “cries out for a maximum sentence.”  Parsons cited the murderer’s infliction of excessive bodily harm, the callousness of the crime and Norton’s high degree of cruelty.    The judge said Norton would continue to be “a serious danger to society” when he sentenced him to state prison and ordered that he be forbidden to have contact with his children indefinitely.

  • This case is old & while I do believe the husband should be where he is for initiating the death of his wife however I can total believe (just not understand) how law enforcement was so lazy that the Baby momma never got a second look at as a suspect & is potentially lounging around freely. It’s one thing to accuse someone who may be innocent but it’s worst to convict someone with the same level of potential innocence. Wasn’t her blood also found at the scene??? Please correct me if I’m wrong.

  • I belive that the prosecuters showed a good example of how they can make up any type of story to explain what they cant really explain. And how the courts go along with it. I believe both the husband and mistress should be in jail. But in thier quest to win a case. The prosecutors failed to fully investigate the mistress. And thats sad because, her husband is where he should be simply because he initiated his wifes death. But the mistress who may actually be the knife welder is free. I feel sorry for his children, caused they had to testify about this horror. I believe his son @13 when he said he saw his father holding his mother down. But I wonder, how many times has one killer hid while on was seen?

  • I’m watching this on Fatal Attractions right now. It seems as though this monster should’ve gotten life without parole or death.

  • the jury barely blinked and convicted him.
    the first case took weeks of discussion.
    what a waste
