CARIBOU, Maine (AP) -- A 19-year-old coffee shop employee kicked his female supervisor in the head and chest, then served customers while the victim died in the bathroom, according to an affidavit released Tuesday.
Christopher Shumway appeared in court for his arraignment on a murder charge Tuesday and was jailed pending a bail hearing.
Shumway told detectives he killed Erin Sperrey, 20, during an argument Sunday night when they were the only employees at the Tim Hortons coffee shop in Caribou, according to the affidavit.
He said he followed Sperrey into the restaurant's freezer, pushed her down and took her car keys, but later returned them, police said.
Shumway told police the struggle resumed when she tried to leave. He said he started to strangle Sperrey, then kicked her in the head and chest and left her bleeding in the coffee shop bathroom. He went to wait on customers and when he returned, she was dead.
Shumway said he dragged Sperrey to her car and drove south before spinning off an interstate near Lincoln. Her body was discovered hours later in the rear seat of her car.
Shumway was arrested Monday at a Motel 6 in Bangor, where police said he apparently tried to hang himself.
The police affidavit quoted the manager of the coffee shop as saying that about $1,200 was missing, but police stopped short of saying robbery was the motive for the killing.
"We probably have some thoughts, and what they are is thoughts," Lt. Dennis Appleton said.
