A woman already accused of killing her 5-year-old son was charged today with a second count of murder involving her 16-month-old son. Michael Dixon, Jr., who was shot multiple times last week by his mother La Tonya Ann Dixon, died October 23 after being taken off life support.

Los Angeles County Prosecutors also added a second charge of assault on a child causing death as well as a special circumstance allegation of multiple murder that makes the 26-year-old mother eligible for the death penalty.

Dixon is charged with killing her 5-year-old son, Christian, and toddler, Michael, at her

apartment in the 7800 block of Gramercy Place about 8:30 a.m. Oct. 17, about 30 minutes after calling 911 to report that she had shot her kids. Patrol officers said Dixon was standing on her second floor balcony and waving a gun around. She asked police to shoot her. She was quoted as saying: “I've wasted my life!''

Police were able to get her to put the gun down, before they rushed her. Police found the children in the living room of the one-bedroom apartment. One neighbor told the LA Times that Dixon was heard around 4:30 a.m. yelling “I'm tired. I'm tired.''

Dixon is scheduled to be arraigned Nov. 2 at the criminal court building in downtown Los Angeles. Anyone with information should contact LAPD's Abused Child Unit at 213-486-0570.
