Motive in Mother's Murder Suicide Attempt Still a Mystery

A Concord woman who apparently stabbed her 10-year-old  daughter Tuesday morning before turning the knife on herself has been  identified by the Contra Costa County coroner's office as 38-year-old Xuan  Liu.
     
Police received a call at about 7:40 a.m. reporting a possible  deceased person inside a home in the 1400 block of Park Glen Court, Concord  police Lt. Jim Lardieri said.
     
When they arrived, officers found a 10-year-old girl who told them  that her mother was dead inside their residence.
     
Officers entered the home and found Liu in a bedroom. She was  pronounced dead at the scene, Lardieri said.
     
The girl told officers that her mother had woken her up and  assaulted her with a knife, Lardieri said. The girl struggled with her mother  and was able to break free, he said.
     
Her mother then appears to have killed herself with the knife and  the girl called 911.
     
An autopsy was being conducted on Liu's body this morning, a  deputy coroner said.
     
Nobody else was home at the time of the attack.
     
The girl was taken to a hospital and was listed in serious but  stable condition, Lardieri said. She remained in the hospital today.
     
Police this morning were not releasing further information about  what may have led to the attack.
