The names of the suspect — who was apprehended soon after the attack ؅— and the victims were not identified by law enforcement authorities because of the ongoing investigation, said Miami Police Chief Manny Morales during a press conference on Thursday afternoon.

The suspect does not have an arrest history in Miami, but he has had “minor criminal run-ins with the police” in New York, Manuel A. Morales, the chief of police for the Miami Police Department, said at a news conference on Thursday. The man’s place of residence was not immediately clear.

A man wielding a stick attacked multiple homeless people in Miami on Thursday, leaving two dead and two injured, according to police. “This is a horrible incident,” Miami Police Chief Manny Morales told reporters. “The officers on the scene and the Miami Police Department is appalled at this display of unprovoked violence.”
