The sheriff’s department said they would like to to speak with 22-year-old Robert Allen.

Last week, XXXTentacion was shot and killed outside the Riva Motorsports store in Deerfield Beach.

The 20-year-old, whose real name is Jahseh Onfroy, was killed as he left the store. The sheriff’s office said he was ambushed by two suspects as he left in his electric BMW. He was shot and killed in the front seat.

Onfroy’s attorney, David Bogenschutz, said investigators told him the rapper had visited a bank shortly before the shooting and possibly withdrew cash to buy a motorcycle. Witnesses say the suspects stole a Louis Vuitton bag and fled in a dark SUV.
