A man has been arrested in connection with the shooting deaths of two men Sunday in Livermore, police said.

The shooting happened in a residential neighborhood on Altamont Creek Drive near Winding Stream Drive about 4:30 p.m.

Officers responding to reports of a disturbance found two men in their 20s who had been shot, police said.

One man died at the scene, and the other died at a hospital. Their names were not immediately released.

The suspect, also in his 20s, fled in a vehicle but was arrested about 9 p.m. near Bluebell Drive and Springtown Boulevard, several miles from the crime scene, said Livermore police Sgt. Steve Goard. His name wasn’t released.

Goard said the killings were an isolated incident involving three men who knew each other, and that the public was not at risk. “There was some sort of confrontation that ultimately led to a shooting,” he said.

Goard said the men had no apparent connection to the neighborhood and that it was unclear what brought them there.

A gun was recovered on Herman Avenue, outside the Kingdom Hall of Jehovah’s Witnesses, less than a mile from the shooting, police said.

The killings are the first homicides in Livermore since 2012.

“We do have a relatively quiet town,” Goard said. “This is very rare, and it happens everywhere, but when it does happen (in Livermore), it’s very sporadic.”

Goard said the police have not determined what caused the death of Marjorie Hillerman, 61, of Mesa, Ariz. Hillerman was found unconscious with a head wound in December in the parking lot of the Livermore Premium Outlets mall, where she was working as a mystery shopper.
