SAN DIEGO (KGTV) - A search for a homicide suspect prompted an early morning SWAT standoff in Ocean Beach Wednesday.
San Diego police told 10News officers were called to an apartment in the 5000 block of Niagara Avenue at around 4 a.m. as part of a welfare check.
A man notified police that he had not heard from his mother and asked officers to visit the apartment.
Once there, officers found a woman dead in the garage, according to police. The identity of the deceased woman was not immediately confirmed.
The man told police he spotted his brother -- identified as 36-year-old Daniel Chase McKibben -- running from the scene.
Police, believing McKibben was still on the apartment complex grounds, summoned a SWAT unit to surround the area shortly before 5 a.m.
The suspect search, which included numerous SWAT officers in tactical gear, forced several apartment units to be evacuated.
The intersection of Bacon Street and Niagara Avenue, where Poma's Italian Deli is located, has been blocked off.
McKibben is white and was last seen wearing a tan shirt and black shorts. He was carrying a backpack, police said.
Police are unsure if McKibben is armed, but they are urging anyone who knows of his whereabouts to call 911.
