CHEYENNE, Wyo. (AP) - A Cheyenne man accused of shooting a 19-year-old man in the head and dumping his body in a Wyoming reservoir has pleaded guilty to two federal firearms charges.

KGWN-TV reports Armando Ramirez-Serna pleaded guilty Tuesday to robbery of a controlled substance by threatening with a gun and carrying or firing a gun during a violent crime causing death.

Authorities say he killed Justin Robinson in November 2017, dumped his body in a reservoir east of Cheyenne and burned Robinson’s SUV.

Federal prosecutors dropped two other charges in exchange for his guilty plea. They have agreed to not seek the death penalty and will recommend a sentence of 40 years in federal prison.

Ramirez-Serna is scheduled to be sentenced in mid-December.
