The FBI, which is leading the probe into the incident, is urging members of the public to submit evidence.
During the press conference, Brett Skiles, the special agent in charge of the FBI’s Miami field office, said: “If you live in the area of the shooting, please check your exterior cameras for last night, early this morning.
“If you see anything that looks suspicious or out of place, please contact us… call FBI or contact the West Palm Beach Sheriff’s Office.”
