LYNCHBURG, VA (CBS/WDBJ) -- New details about the Campbell County, Virginia man, accused of killing his grandparents. Surveillance video shows Robert Philbrook at a Lynchburg pawn shop, selling his grandparents jewelry right around the time deputies believe they were shot to death.
Workers in the store say Philbrook was calm. He told them that he'd recently lost his grandparents, but said nothing about how they died.
He walked in to the Lynchburg Pawn Shop on Fort Avenue last Tuesday, the same day investigators believe his grandparents were killed. Surveillance video shows him carrying a tote bag. Workers in the store say it was full of jewelry.
Most of it was costume pieces, but some of the items were made of gold and silver, including a diamond ring from the 1920's.
As workers reviewed the items, Philbrook told them stories about seeing his grandparents wear the jewelry. The pawn shop manager, Sean Hardy, says Philbrook seemed suspicious. He contacted Lynchburg police, while Philbrook was in the store.
An investigator ran a background check, to see if the items were stolen. Pawn Shop manager Sean Hardy says, "I was concerned, obviously not about murder at that point, but what was going through my head was that this jewelry didn't belong (to him). I wasn't really buying his story on where he got the jewelry from."
The background check showed Philbrook was convicted of drug charges in 2005, but that wasn't enough to stop the sale from going through. He was paid more than $1,400 and used part of the money to buy a "mother and child" pendant in the store.
After getting the money, Philbrook may have gone back to his grandparents' house. Search warrants indicate that the tote bag used at the pawn shop was later found next to Virginia Philbrook's body.
