Volunteers searching for signs of 25-year-old Austin Hart confirmed the family's worst fears. Police are now investigating the man's death, and how his body ended up under a pile of tires. 

The discovery happened near the intersection of Neal Place and Temple Street in Atlanta, Thursday afternoon.

The search ended tragically, after Hart's mother spent much of Wednesday in  Northwest Atlanta searching for her son who disappeared under suspicious circumstances.

"I wanted to see- I wanted to have closure," said 18-year-old Preston Wysocki, the youngest brother of Hart, who came to the scene with his family. "We are both of course, very overwhelmed. We are holding it together as well as we can," he said.

The discovery came about, thanks to volunteers who handed out fliers by the neighborhood where the body was found. A group called the Mob motorcycle club, which volunteers their time to find missing and exploited children, said neighbors told them where to find the body.

Police believe Hart could have died of a drug overdose, but are investigating who put tires on top of the body.

Atlanta police said Austin Hart's car was found in the same neighborhood she and others were searching.

Mother, Heather Wysocki, told FOX 5 earlier this week, she last saw Hart on Sunday morning when he left the home they share in Acworth to go to his girlfriend's home in Atlanta's Virginia Highland area. However, his car turned up near at Paines and Pelham in Northwest Atlanta.

Atlanta police said a stranger sent text messages to Hart's younger brother, Preston, who then called the man back.

She said she came to the area, described as a hot bed of heroin activity by Atlanta police, because Austin has been battling a heroin addiction.Ms. Wysocki said he had been clean and sober for the last year, but was having trouble coping Saturday.
