HAVERHILL (WBZ-AM) -- On the day police say he shot and killed a police deputy in Norridgewock, Maine, a man currently being hunted by police was supposed to be in court in Massachusetts.
John Williams, 29, was out on bail after being arrested in March in Haverhill for possession of an unlicensed gun.
Maine police say that on Wednesday, the day he was due in court, Williams shot and killed Somerset County Cpl. Sheriff Eugene Cole, stole his cruiser, and robbed a convenience store.
As the manhunt for Williams continues, authorities are warning the public to be on the lookout for him.
"The suspect should be considered extremely armed and extremely dangerous," Somerset Sheriff Dale Lancaster told reporters Wednesday.
Officers surrounded a home in Madison, Maine Wednesday night--Williams' last known address--but said he is still on the loose.
"If people encounter him, they should not approach him, they should call 911," Maine State Police Lt. Col. John Cody said. "Just be aware of their surroundings, because he does continue to pose a risk."
Cpl. Cole is the first officer in Maine shot and killed since 1989.
