SPOKANE, Wash. — A dispute over a Beatles poster led to the killing of a man whose body was found in the Spokane River, police say.

In an affidavit filed to obtain an arrest warrant, police wrote that Robert A. Entel Jr., 18, told investigators he strangled Bud Robert Johnson, 45, with a computer cord.

By contrast, Entel’s roommate, who said Entel is her cousin, told officers he talked of holding Johnson’s head under water in the river. She said he told her watching the last bubbles rise to the surface was “better than sex,” investigators wrote.

Entel was described as 6-foot-3 and about 200 pounds, while Johnson, a diabetic, as 5-foot-4 and 140 pounds.

Something tells me that this young man was a virgin.
