The witness said he got a bad feeling when he noticed the guy was lurking around. They said the stranger followed them to a car deck around the corner.
"He started yelling obscenities, such as 'Hey, which one is with who? I wanna have sex with one of you guys.' He then screamed that he was homeless and that he wanted to know if one of us could give him some money," the witness told WSB-TV.
The witness said he gave him $5 hoping he’d go away but it just made things worse.
"He literally pulled up his shirt and pulled out a gun," the witness said.
Most of the group ran but the witness and one friend were in shock. They said the gunman forced them to undress and the friend decided to run.
"He shot twice, shot him in his back twice," he said.
The victim is still in the hospital.
