The incident occurred shortly after 7:30 a.m. in the 32000 block of Alipaz Street, near Del Obispo Street, after deputies responded to a domestic assault call. Video from AIR7 showed deputies and two patrol vehicles in an area cordoned off by crime tape.
When they arrived, they found two people dead inside a home - only identified as a 77-year-old man and a 79-year-old woman. They also found a dead dog.
The grim discovery prompted a search for a suspect, who was eventually located along a bike path in the area.
During a news conference Tuesday, Sgt. Matthew Parrish provided details about how they found him: "Our dispatchers updated them that there was a bloody male chasing a maintenance worker in that same neighborhood.... Shortly after that person was located, an officer-involved shooting occurred."
The 41-year-old suspect was taken to the hospital in serious but stable condition.
Investigators are looking into the connection between the suspect and victims.
