Local police and Federal Marshals are trying to hunt down the men they believe helped Dedrick D. Williams kill XXXTentacion.

They have just named a second person of interest. 

22-year-old Robert Allen is seen on surveillance video at the motorcycle shop in Deerfield Beach, Florida where XXX was shopping before getting gunned down as he was leaving in his car.

Police believe the motive behind XXXTentacion killing was robbery.   After X was killed, one of the suspects reached into X's car and grabbed a small bag, which likely contained cash XXX brought to the motorcycle shop.

Update: Allen has quite the criminal past. According to TMZ:

22-year-old Robert Allen's rap sheet in Broward County, FL dates back to early 2015, when he was hit with 3 felony charges after being pulled over for riding without a seat belt. He was charged with trafficking cocaine, carrying a concealed firearm and grand theft of a firearm. 

Later that year, two warrants for his arrest were issued for allegedly carrying PVP (a synthetic party drug) and carrying a concealed firearm. He was charged with the 2 felonies.

Allen was also hit with 22 felonies in 2016 (yes, you read right) ... all of which pertained to IDs and credit card info he was accused of stealing. He was just placed on probation for 45 months this past December.
