Homicide detectives are looking for a man suspected of fatally stabbing an 87-year-old woman and injuring her 60-year-old daughter last week at a Mira Mesa home, police said Thursday.
Investigators believe the April 22 attack was not random and that the suspect, Anthony Dwayne Siddle, 59, knew the victims, according to San Diego Police Lt. Jud Campbell.
But Campbell said he could not comment on the specific relationship between Siddle and the victims.
Detectives believe Siddle may have fled to Mexico, Campbell said in a news release. Siddle is suspected of killing Peggy Brandenburgh and seriously injuring his unnamed daughter, who is expected to survive her injuries.
The knife attack happened just before 3pm on Pagoda Way, a short residential street parallel to Gold Coast Drive near Westonhill Drive. The 911 caller – police did not say who made the call – told police that several people had been stabbed.
Brandenburgh died at the scene and paramedics took the other woman to a trauma center to treat her injuries, police said last week.
Campbell did not elaborate on how detectives identified Siddle as a suspect and said the motive for the attack is still under investigation.
“Initial information indicates that the suspect entered the residence and immediately stabbed both victims,” Campbell said in the news release.
Police described Siddle as white, about 6ft 3in and 165lbs. He has gray hair, wears glasses, and was last seen running away from home wearing a brown shirt and blue jeans. He was driving a dark gray 2018 Ford Ecosport — a small SUV — with Montana license plates of 103478E, and was possibly heading to Mexico.
“Siddle should be considered armed and dangerous and should not be approached,” Campbell said, adding that detectives had obtained a warrant for Siddle’s arrest.
Anyone who sees Siddle is asked to call 911. Anyone with information on his whereabouts is asked to call the San Diego Police Department Homicide Unit at (619) 531-2293 or San Diego’s Anonymous Tip Line. San Diego County Crime Stoppers at (888) 580-8477.
