Murder Suspect Javaris Crittenton Someone Jacked My Jacket!

Former NBA player Javaris Crittenton may have thought being charged with murder was the worst thing that could have happened to him this year ... until someone stole his $6,000 Gucci jacket.

Law enforcement sources tell TMZ ... Crittenton -- who's still out on bail for allegedly shooting a woman to death back in August -- was hanging out at Drai's nightclub in Hollywood last weekend ... when he decided to put his jacket down and didn't keep an eye on it.

We're told Crittenton went to grab his jacket on his way out of the club around 1:00 AM ... when he discovered it was MISSING!!

Crittenton -- who went MIA for a few days after he was charged with murder -- decided this time, he would seek out the police ...and reported the theft to the LAPD.

We're told cops are investigating the alleged jacket heist.

If Javaris replaces the jacket, he may want to get it in orange.
