REDWOOD CITY (Map, News) - The last time Quincy Mack Norton saw his mother alive, she was sprawled out faceup, pinned down by his father on the couple’s bed, the 11-year-old testified Monday.

The boy recalled running across the hall to his parents’ bedroom after hearing his mother scream his and his brother Dion’s names in a frightened voice on July 22, 2006, and seeing his father, Quincy Norton Sr., restraining Tamika Mack Norton.

“I was just screaming,” Quincy Jr. said. “My dad told me to go back in my room.”

Quincy Jr., the only person to witness the confrontation on the morning of the killing, then testified that he heard “banging and bumping noises” coming from the room. Minutes later, his father came into his bedroom, shut the door, and told him to get dressed, Quincy Jr. said.

Quincy Jr. said he had learned to recognize when his father was drunk and he seemed like he had been drinking that morning.

“His eyes were red and he kind of smelled,” he said.

Norton, a 33-year-old Daly City man, was arrested a month later in the fatal stabbing. He faces life in prison if convicted.

Throughout the murder trial, Deputy District Attorney Al Giannini has painted him as a batterer and chronic philanderer who had a child with one mistress, Anitra Johnson. Giannini said he was driven to kill Tamika Mack Norton when she finally filed for divorce.

Quincy Jr. also testified that when he was in kindergarten, he heard an argument between his parents in which his father threatened to cut off his mother’s hair. The next day, Quincy said, his mother’s face was red. His father later apologized to him for hitting his mother, he said.
