Local detectives are in Oklahoma hoping to talk to the grandson of an elderly couple found dead in their Pikesville home last week.
Baltimore County police say Matthew Long is a suspect in the murders of Vaughn and Marjorie Pepper.
Long is at a hospital after he overdosed in an Oklahoma hotel room.
When police took him to the emergency room, his name came up in the system as a person of interest.
Investigators say they haven't been able to talk to him yet because of his condition.
