EL CAJON, Calif. — A man was arrested Tuesday on suspicion of stabbing a 54-year-old man to death in El Cajon, authorities said.

Daniel Perez, 30, is in police custody for a separate assault and burglary, but he has been additionally charged with the Aug. 22 murder of Patrick Heard.

According to El Cajon police, they received information through Crime Stoppers tips that indicated Perez was a possible suspect in the homicide of Heard. Detectives investigated and concluded probable cause existed to seek additional charges of homicide against Perez.
