Two people are dead in what appears to be a murder-suicide, according to police.
"At 6:36 p.m. we received a report of gunshots in the 2100 block of Alameda Avenue," Lt. Joe McNiff said. "Officers responded and found a woman and a man. The woman was pronounced deceased at the scene. The man was transported to a local hospital."
The man was pronounced dead at 1:44 a.m. this morning, according to a Bay City News Service report.
Bay City News also reported the woman was 30 years old and the man was 36.
The man and woman apparently had previously been in a romantic relationship, police said.
Several people commented on Alameda Patch's Facebook page that they heard the shots Monday evening.
"Gun shots heard on corner of Walnut & Alameda Ave.," wrote one.
"A neighbor heard 4 gunshots," wrote another.
A woman, who parked in the area shortly after the shooting, wrote that she saw police enter a home and, later, she saw a coroner's van.
"[I] parked right near there on my way to a class tonight, saw a number of police rushing in to a house," she wrote. "When I left, a coroner's van was there and the area was still being monitored by police, one policeman standing out in front of the house, and it was all cordoned off with 'crime scene' tape."
Around 7:30 p.m. the Alameda Police Department tweeted that there was a "Police activity 2100 blk Alameda Ave" and advised residents to "avoid the area."
"The investigation is ongoing," McNiff said.
