SAN JOSE — Police fatally shot a heavily armed man who fired multiple rounds at officers Sunday afternoon at a home near Guadalupe Oak Grove Park, according to authorities.

Officers had been responding to a call of a family disturbance when the man pointed a gun at officers, San Jose Police Chief Paul Joseph said at a news conference Monday. Following attempts to de-escalate the situation, the man shot at officers in front of the house and in a neighboring yard, when he was then fatally shot by an officer, Joseph said.

Officials on Monday identified him as Karim Kahn, 37. Police said Kahn, who had unspecified mental health issues, was living in an ADU behind his parents’ house in San Jose and became physically aggressive toward his parents while off his normal medication, Joseph said.

“This incident is a tragedy, primarily because there was such easy access to firearms during the mental health crisis,” Joseph said. “These calls are always unpredictable, but are too often among the most dangerous situations our officers face. They escalate without warning.”

Around 2:24 p.m., the San Jose Police Department responded to a call on the the 5800 block of Recife Way, where Kahn was throwing objects at his parents, Joseph said. The initial call did not report that Kahn had weapons, and the response included officers with crisis intervention mental health training to attempt to stabilize the situation.

As officers walked through the side yard toward the ADU, Kahn exited the structure and pointed a long gun at them before fleeing behind the residence, Joseph said. Officers went back to the street to develop a plan for de-escalation, he added.

“By immediately pointing a firearm at officers, the man created an incredibly dangerous and volatile situation for everyone involved,” Joseph said.

The responding officers called Kahn’s phone number to attempt to convince him to leave his gun and come outside, but Kahn hung up after about 20 minutes, Joseph said. As four officers took cover behind a patrol car, Kahn emerged from the side yard and fired at least one round in their direction before fleeing back behind the house.

The bullet hit a patrol car’s fender, Joseph said. Investigators believe that the car’s engine stopped the bullet from striking officers, he added.

Meanwhile, more officers had positioned themselves in the yard of the home behind the property where Kahn was, Joseph said. After Kahn jumped the fence into that yard, armed with a shotgun and a rifle, he exchanged gunfire with an officer. One of Kahn’s bullets hit the house “directly next to” the officer, Joseph said.

Kahn fell onto a raised planter, obscuring officers’ ability to see whether he was still holding the guns, Joseph said. When officers approached, they saw he had been hit by at least one gunshot. Kahn was pronounced deceased at the scene.

Police found that Kahn had four firearms and at least 50 rounds of ammunition on him, Joseph said — a rifle, a shotgun, a revolver and a semi-automatic handgun. He was also wearing hearing protection, which was “possibly indicating he was anticipating a gunfight with police,” he added. When officers searched his residence, they found firearm parts, loaded magazines and additional ammunition.

The firearms were not registered to Kahn and investigators are still looking into how he acquired them, Joseph added. SJPD had previously had some contact with Kahn but Joseph declined to share whether he had a criminal history.

“My heart goes out to the family who lost a loved one yesterday. I’m truly sorry for your loss,” Joseph said. “Weighing incredibly heavily on me is that last night, I came very close to visiting multiple officers’ families to deliver tragic news about their loved ones. Seeing the bullet holes inches away from where my officers were standing is chilling.”

The officer who discharged his gun has been on the force for eight and a half years, Joseph added. He had been trained with the Crisis Intervention Team and wore an activated body camera.

“I’m extremely grateful no officers were hurt or killed yesterday, and I know that it was a combination of tactics and luck that made that possible,” Joseph added. “No officer wants this to be the outcome in a situation like this. While no officers were harmed, the officer who defended their life and those of their partners will be affected by this for the rest of their life.”

There will be an investigation into the officer-involved shooting conducted by the Santa Clara County District Attorney’s Office, Joseph said. The case will also be monitored by SJPD’s Internal Affairs Unit, the City Attorney’s Office and the Office of the Independent Police Auditor, he added.
