Tyrone David Lopez, 40, was found dead in his Alhambra home on January 7, 2017. Los Angeles County coroner’s records state he was discovered with a gunshot wound to the head in his bedroom in the 2800 block of West Alhambra Road; police were called about 6:15 p.m. and Lopez was pronounced dead at 6:36 p.m. Authorities ruled out suicide and treated the death as a homicide from the start.

Lopez’s mother, Rachel Hernandez, found his body after returning from work. Investigators reported a single bullet casing in the room but did not recover a weapon. Friends and family, who held a funeral at Holy Family Catholic Church in South Pasadena, described Lopez as trusting and big-hearted and said they feared the killer could be someone they knew.

No suspects have been identified and the investigation remains open. Can anyone who knew Tyrone or who has information about that night contact the Alhambra police?
