Tyron N. Arthus, 24, of Fort Lauderdale, was shot to death on October 8, 2021, on Interstate 595 near Hiatus Road in Davie. He was found lying on the shoulder of the eastbound lanes and was pronounced dead at the scene by Davie Fire Rescue. According to the investigation, Arthus had been riding in a vehicle with 17-year-old Marcus Ramone Cooper Jr., who ordered Arthus out of the car and shot him multiple times.

An arrest warrant was issued charging Cooper with first-degree premeditated murder with a firearm. Authorities described Cooper as armed and dangerous and said his whereabouts were unknown; the Broward Sheriff’s Office has asked the public for help locating him. Investigators reported Arthus and Cooper had a personal relationship and may once have been friends, but the motive has not been determined. Arthus’s mother, Marie Arthus, publicly appealed for justice.

If anyone knew Tyron, his movements that night, or has information about Cooper’s location, please share what you know with the Broward Sheriff’s Office.
