Police in Pinole on Monday morning detained a possibly armed man in a neighborhood around Shannon Elementary School after a standoff that prompted an area lockdown, according to the police department.
The 32-year-old man, who police determined was armed with two handguns, wasn't threatening officers, himself or others, and was taken to a hospital for a mental health evaluation after he peacefully surrendered, police said.
Late Sunday night, police responded to a call from the man's mother as well as from a neighbor who reported hearing gunshots, police said. During a welfare check, officers found a dog shot to death inside the house.
Police later found the man on foot in the neighborhood, prompting the lockdown.
At the start of the shelter order, people on Kildare Way between Marlesa Road and Tara Hills Drive and on Barkley Court were advised to lock down in the nearest place of safety, police said. They were instructed to stay inside and close and lock all windows and doors until further notice.
Police also advised residents to stay off the phone and not call 911 unless they need to report a life-threatening emergency.
Shannon and Tara Hills elementary schools were closed for the day, and nearby Pinole Middle School was operating on lockdown during the incident, according to officials with West Contra Costa Unified School District.
