Police reported Monday they have arrested a mother who they believe killed her 2-month-old daughter in a Grantville apartment.

San Diego Police homicide detectives responding to a welfare call in the 10300 block of San Diego Mission Road at 11:33 a.m. on Sunday arrested 35-year-old Christine Mendoza on suspicion of killing her 2-month-old daughter.

The infant suffered trauma to her body that indicated she was the victim of violent trauma, police said.

Lt. Steve Shebloski described the crime as “a tragic domestic-related incident where the infant’s mother killed her child for unknown reasons.”

Mendoza was booked into San Diego County jail on one count of murder.
