CHARLOTTE, N.C. -- More than 50 hours have now passed since 24-year-old Kyle Fleischmann walked out the door of uptown Charlotte's Buckhead Saloon.

It's been 50 hours of agony for his family. On Monday afternoon they retraced his steps, with no idea where he could be.

“It's possible he came across some people. He's a well-dressed, good-looking guy -- may have tried to rob him, I don't know,” said Dick Fleischmann, Kyle’s father.

The last time he was seen, Kyle Fleischmann was at the Buckhead Saloon with friends last Thursday night. They'd gone to the bar after a concert, but some time during the night, Fleischmann became separated from those friends.

Police are now studying a grainy surveillance video that shows Fleischmann walking out the door and toward Tryon Street. But three days later, they still have no solid idea of where he is.

On Friday Fleischmann didn't show up to work at a SouthPark office building, so over the weekend his family began putting up pictures outside the Buckhead Saloon.

Then Monday friends including Cristyle Wood joined in, hoping they might uncover some hidden lead.

“Hopefully someone has seen something, or saw him leave, and they know who he was with. Something like that,” she said.

Fleischmann’s family said it has hired a private detective to join the search, and their worry has turned to grave concern.

“The fact that he hasn't contacted us leads you to believe the worst,” his father said.

Dick Fleischmann said there’s been no activity on Kyle’s cell phone or his bank account, and he had no reason to run off anywhere. His mother just found out she has cancer and has surgery scheduled for this week; Kyle had been calling her every day.

If you see Kyle Fleischmann or have any idea what happened to him, call police immediately.
