EDITOR’S NOTE: The San Diego County Sheriff’s Department initially described the weapon used by the suspect as a “machete,” but later changed the term to a “metal object.”

SAN DIEGO — A suspect in an attack that left two injured was fatally shot by San Diego police Tuesday after lunging at an officer, authorities said.

Just after 8 a.m., police received a call of an assault with a deadly weapon at a home in the 1500 block of Bridgeview Drive in the Fairmount Park neighborhood, Lt. Chris Steffen with San Diego County Sheriff’s Department stated in a release. When officers arrived, they located two women, a 73 and 79-year-old, who had been attacked by a person armed with a “metal object” following a verbal argument, Steffen said. One of the women had a laceration on her head and the other, on her neck.

Officers made contact with the suspect, who had barricaded himself inside a bathroom in the home, Steffen said. Authorities were able to open the bathroom door and attempted to use pepper spray on the suspect but it was ineffective.

Officers eventually used a police K9 to try to apprehend him.

“At some point during that incident, the K9 was struck with some sharp object, wherein an officer was also assaulted with a sharp object,” Steffen said. “It’s still unclear if it was the machete used against the victims or another type of weapon.”

An officer fired one round at the suspect, wounding him. The suspect was taken to a hospital, where he was pronounced dead.

The victims were taken to a hospital, where they are expected to survive, Steffen said.

No officers were injured. The police K9 was being treated and was expected to be OK.

Authorities say the suspect is believed to be the nephew of the victims. The suspect was identified only as a 48-year-old man.

The 1500 block of Bridgeview Drive was expected to be blocked off for six to 10 hours while police investigate.
