An arrest warrant had been issued for Twane Dobard after the body of 58-year-old Domenico Perruccio was found early Sunday on a sidewalk in Hollywood, Florida.
Police spokesman Lt. Osvaldo Perez said the victim had been stabbed during "some sort of scuffle" and that the death was ruled a homicide.
Perruccio's hometown was not immediately known.
Dobard turned himself in to Hallandale Beach police at about 9 p.m. Monday. It was unclear what charges he may face.
Local reports had quoted neighbours as saying Perruccio was waiting for his wife to arrive because the couple were supposed to leave on a cruise on Monday.
Perez said police have notified Perruccio's family and Canadian consular officials.
