TITUSVILLE, Fla. —

Titusville police may have found the person who ran over a woman, and left her in the road to die. Investigators believe a note found inside a car at the scene may hold all of the answers.

Thursday morning, Titusville police were called to the Causeway near U.S. 1 and Garden Street to check a suspicious silver car. Inside, they found Mark Maddox, 53, dead from an apparent suicide.

Sources close to the case said Maddox left a note, which said he felt bad because he'd been in a car accident where someone was badly hurt.

That someone may have been Christina Rosten, 38, who was involved in a recent hit-and-run accident.

The landlord where Rosten formally lived told WFTV what he knew about the accident scene.

"I heard from a person that was there at the scene and they said it was gruesome," said Jeffrey Gillis.

Gillis said he heard about an accident early Sunday morning, where a woman was run over. However, he had no idea that it was someone he knew.

"She was always smiling, pleasant and just happy-go-lucky. It's a real tragedy," said Gillis.

Police are unsure why Rosten was already lying in the road when the car hit her.

For days, authorities have been looking for a silver or grey Chevy Malibu.

So far, detectives won't say if Maddox is the person who hit and killed Rosten. They also won't confirm if the car found on Thursday was definitely involved.

Titusville police are currently investigating whether the two incidents are connected.

Gillis said if Maddox is the hit-and-run driver, he couldn't imagine being in his situation.

"I couldn't possibly conceive of carrying that burden. I wouldn't see any way of for a person if they felt that much guilt, other than to turn themselves in and maybe he didn't want to."

Maddox worked at the Air Force Station in Cape Canaveral.

The hit-and-run victim is still in the hospital with critical injuries.
