A Billings man admitted to charges Thursday for a string of four armed robberies.
William Ray Everhart, 32, appeared before District Judge Susan Watters and pleaded guilty to three felony robbery charges and one count of attempted robbery.
A plea agreement states prosecutors will ask for a total sentence of 20 years at Montana State Prison, with 10 years suspended. Felony robbery carries a maximum prison sentence of 40 years.
Everhart remains in the county jail. He is scheduled to be sentenced July 29.
Everhart admitted to robbing the Subway on King Avenue on Oct. 12. Employees said the robber was armed with a handgun.
Two days later, Everhart committed a string of three robberies within 30 minutes. The first robbery happened at about 5 p.m. when a man armed with a black handgun entered the Dairy Queen on Henesta Drive.
An employee fled to the back of the restaurant, and Everhart left without any money.
About 10 minutes later and a half-block away, Everhart robbed Versa Tan. He then moved to Pie Guys Pizzeria on King Avenue West.
Everhart was arrested as he fled the last robbery. A black pellet gun that appeared to be a real firearm was found near where he was arrested.
