Homicide detectives are searching for a man suspected of fatally stabbing an 87-year-old woman and wounding her 60-year-old daughter last week inside a Mira Mesa home, police said Thursday.
Investigators believe the April 22 attack was not random and the suspect, 59-year-old Anthony Dwayne Siddle, knew the victims, according to San Diego police homicide Lt. Jud Campbell.
But Campbell said he could not comment on the precise relationship between Siddle and the victims.
Detectives believe Siddle possibly fled to Mexico, Campbell said in a news release. Siddle is suspected of killing Peggy Brandenburgh and critically wounding her daughter, whose name has not been released and who is expected to survive her injuries.
The stabbing attack occurred just before 3 p.m. on Pagoda Way, a short residential street that runs parallel to Gold Coast Drive near Westonhill Drive. The 911 caller — police have not said who made the call — told police that multiple people were stabbed.
Brandenburgh died at the scene and paramedics took the other woman to a trauma center for treatment of her injuries, police said last week.
Campbell did not say how detectives identified Siddle as the suspect and said the motive for the attack remains 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 6 feet 3 inches and 165 pounds. He has gray hair, wears glasses and was last seen fleeing the home wearing a maroon shirt and blue jeans. He was driving a dark gray 2018 Ford Ecosport — a small SUV — with Montana license plates of 103478E, and possibly headed to Mexico.
“Siddle should be considered armed and dangerous and should not be approached,” Campbell said, adding that detectives obtained a warrant for Siddle’s arrest.
Anyone who sees Siddle is urged to call 911. Anyone with information about his whereabouts is asked to call the San Diego Police Department’s homicide unit at (619) 531-2293 or San Diego County Crime Stoppers’ anonymous tip line at (888) 580-8477.
