STERLING, Colo. (CBS4) - Police have arrested a 19-year-old accused of killing his grandparents in the town of Sterling in eastern Colorado.
Brendan Lee Johnson and his girlfriend Cassandra Ann Rieb, 18, face charges of first-degree murder, aggravated robbery, forgery and theft.
Investigators say part of Shirley Anne Severance's remains were found near Sterling and near Lorenzo, Neb. Her husband, Charles Severance, was found dead in their home last weekend.
"Investigator teams are processing both crime scene locations where the remains were found. One of the locations is at the Prewitt Reservoir, which is located approximately 18 miles southwest of Sterling along Highway 6," Sterling police said in a statement. "The second location is several miles west of Lorenzo, Neb."
Lorenzo is located just across the state border.
Police said no other individuals were involved and there is no threat to the public.
Neighbors said both Johnson and his grandparents were quiet and private.
"It wasn't a big surprise when I found out that he was involved, but I sure didn't, I didn't think it would be that gruesome, I guess," said neighbor Ron McBride.
