The live-in grandson of a slain elderly couple from Pikesville has been named a suspect after Baltimore County detectives located the 31-year-old in Oklahoma.

Police said Matthew Long lived with his grandparents, Vaughn and Marjorie Pepper, who were found dead Monday in their Sudbrook Park home.

Authorities in Oklahoma alerted Baltimore County homicide detectives when Long was found in need of medical treatment. Baltimore County police had issued a missing-person alert on Long, which prompted Oklahoma authorities to contact Baltimore County.

Police spokeswoman Cathy Batton would not reveal the circumstances that resulted in Long's hospitalization.

County homicide detectives have not interviewed Long because of continuing medical treatment but named him a suspect Friday.

Officers were called to the home in the 800 block of Olmstead Road by a neighbor who had been contacted by a concerned out-of-state relative of the victims.

Vaughn Pepper was found lying on the floor and his wife in the basement. Both had what were described as traumatic injuries, but police have not said what the weapon was. Detectives ruled out a shooting.

The Peppers' funeral was scheduled Friday in Dorchester County.

Vaughn Pepper was a retired state police trooper. Before that, he served in the Army during World War II. According to his obituary in the Star Democrat newspaper in Easton, Pepper was injured during the Battle of the Bulge.
