SAN FRANCISCO (AP) — Two people in Union City and nearby Hayward have become the latest to die in a string of separate officer-involved shootings over the weekend, San Francisco Bay area police said.

The deaths were the third and fourth fatal shootings in the Bay Area involving police and suspects in a little more than 24 hours. On Saturday night, a motorist died after pulling a gun on officers during a traffic stop, Union City police said. Another suspect tried to run down a Hayward police officer during a traffic stop early Sunday, police there said.

In the Union City shooting, the driver was shot after he was pulled over by police, tried to flee and then pointed a handgun at officers, said police Cmdr. Ben Horner. The suspect, who was not named, died after being taken to a hospital. A loaded handgun was recovered at the scene, police said.

In the Hayward shooting, Arthur Pakman was pulled over for speeding and reckless driving early Sunday when he tried to run over the officer who stopped him, Hayward police Sgt. Eric Krimm said. The officer opened fire and struck a passenger in the car, Krimm said.

The passenger was also injured in a crash later, police said. The unidentified passenger later died, though it was not immediately clear whether he died from gunshot wounds, the collision or injuries from both, Krimm said.

The officer involved in the Hayward incident was not injured. Pakman fled from the area, but crashed into a sign and a tree planter a few blocks away, police said. He was taken into custody after trying to run from the crash scene, Krimm said.

Pakman was being held on suspicion of assault with a deadly weapon on a police officer and homicide, with the homicide charge coming because Pakman appears to have caused the death of his passenger, Krimm said.

“(Pakman) is the cause of the officer’s actions,” Krimm said. “Had that not gone down, then the officer would not have had to shoot.”

The other two fatal shootings in the Bay area included one in San Jose, where two officers fatally shot a man who rammed three patrol cars during a high-speed chase Saturday, police said. The officers believed the man was armed because he brandished what appeared to be a gun during the chase, Sgt. Jason Dwyer said.

They “felt the suspect presented an imminent danger,” Dwyer said.

The rash of shootings started early Saturday in Daly City, where the driver of a stolen car led police on a chase that ended in San Francisco. The driver jumped out of the car and raised a gun at officers, and a Daly City officer opened fire, said Officer Carlos Manfredi, a San Francisco police spokesman.

The names of the suspects in the San Jose shooting and the shooting involving the Daly City officer have not been released.
