A Southern California man who killed his wife propped up her body on a sofa, told their children she was drunk and had them open Christmas presents in front of her body, a prosecutor told jurors at his murder trial.

Officials say the man killed 26-year-old Za’Zell Preston after the couple got into an argument and she stumbled on a table.

Prosecutors say Wallace dragged his wife’s body from the bedroom to the living room couch, placed sunglasses on her and told the children: “Mommy ruined Christmas, she got drunk and ruined Christmas.”

Preston was slumped over on the couch when paramedics arrived. She left a newborn son and two daughters, who were then 3 and 8 years old.

Wallace’s attorney argued that Preston died from injuries after she drunkenly tripped and fell into a glass table, shattering it.

Wallace, 39, could face up to 25 years to life in prison if convicted of first-degree murder.
