It’s a real mystery. Two middle-aged men were found dead, and somewhat decomposed, inside Unit 70 at the Red Fox Farm Condos.

Police say they see no obvious injuries and there’s no indication of a struggle.

Neighbors want to know what killed them because they find it very odd.

“It’s shocking, especially to find out two at one time,” said Nicki Harward, neighbor. “He was really quiet, nice guy. It’s really shocking to come home from work and find this out.”

The homeowner, Kraig Krixer, 59, is one of the victims. Police say the other is a friend who had marital problems and moved in with Krixer a while ago.

“I believe it was his brother who called them, because he hasn’t heard from them and they came to check on him. That’s when they found the two bodies,” said Lawrence Graveson, neighbor.

After the bodies were discovered, the fire department tested for carbon monoxide to see if that could be the cause of the two men’s death, but that came up negative.

“Right now, we’re investigating as a suspicious death. The bodies have been taken to the medical examiner’s office and the outcome of the investigation will be pending the autopsy,” said Lt. Rob McCullough, Baltimore County Police.

It will come down to science, testing tissue and seeing if some substance is to blame for the suspicious deaths.

Many want to know if the deaths were intentional or an accidental.
