ROSEVILLE, Calif. — A Montana man was identified Thursday as the alleged suspect in multiple shootings across South Placer County that killed an elderly woman and injured one other, sheriff's officials said.

According to the Placer County Sheriff's Office, Stanley Stepanski III, 48, shot at multiple people between Loomis and Newcastle before crashing his pickup truck on Interstate 80 in Roseville. After the crash, Stepanski confronted arresting deputies who then shot and killed him, officials said.

During the shooting, a K9 officer was also struck. The K9 had surgery and is expected to be back with his handler this week.

In his shooting rampage, officials said Stepanski either fired his gun or threatened people at at least seven different locations in South Placer County.

One of the two victims, later identified as 93-year-old Mary Toste of Penryn, died at the hospital. Authorities said Toste was standing at her front door when Stepanski allegedly drove by and starting shooting from his pickup truck.

Neighbors told ABC10 that Toste's husband died last month of pneumonia.
