The FBI has joined the search for ex-NBA player Javaris Crittenton -- who is wanted for murder in the shooting death of a 22-year-old woman.
The feds have announced they are working with police in Atlanta -- where Jullian Jones was shot and killed on August 19.
Cops believe Crittenton was not aiming at Jones -- but rather someone else in the area who may have robbed the former basketball player back in April.
It's unclear if officials have an idea where Javaris may be hiding out -- and the FBI is not releasing any further information.
As TMZ previously reported, Crittenton -- a former member of the Washington Wizards -- was the other man in the Gilbert Arenas locker room gun incident back in 2009.
