The Gilroy Police Department is looking for a woman it believes may be dead or critically injured.
Police were called to the apartment at 9005 Kern Ave. around 9 p.m. after a roommate who lived with the family called police suspecting something was wrong.
Authorities found the body of an 11-year-old Lucero Luna with a gunshot wound to the head and the body of Abel Gutierrez, 27, who appears to have died of a self-inflicted gunshot wound, according to police reports.
Police are now looking for their mother, Martha Gutierrez, 51, who they say left physical evidence that she may be critically injured or dead.
A preliminary investigation appears to show that Lucero Luna had been shot by her older brother, who then turned the gun on himself. She was a student at nearby South Valley Middle School in Gilroy.
Mario Reyez, who lives underneath the Gutierrez family, said he heard a scuffle Wednesday night around the time authorities say the shooting occurred. He did not hear gunshots.
Reyez described "Lucie" as a friendly girl who used to ride bikes with his 6-year-old daughter.
A police report said that Abel Gutierrez was an Iraq war veteran and there were reports that he had been suffering from post traumatic stress disorder.
Police had been called to the home before.
