(CHICAGO) A 28-year old suburban Chicago man has been added to the FBI’s Most Wanted list. Luis Macedo is charged in a brutal 2009 killing on the city’s south side. Macedo, last of Oak Lawn, is wanted in the death of 15-year old Alex Arellano.

The teen was walking with friends in the 3000 block of West 54th Place back in 2009 when Macedo and other members of the Latin Kings gang approached him. Federal officials say Arellano was beaten and shot to death, then his body was set on fire.

Officials say Macedo hasn’t been seen since the attack 7 years ago, and he may be hiding out somewhere either in the southeast or Mexico.

Four other gang members were arrested in connection with Arellano’s death and were either convicted at trial or pleaded guilty to the crime and are already serving prison sentences. FBI Special Agent in Charge Michael Anderson said Thursday Macedo was likely the ringleader of the group that killed Arellano.
