Arietta Marie Tinker, 17, was last seen alive on April 9, 1975, when her husband dropped her off at the Hippopotamus Lounge on Hollywood Beach in Hollywood, Florida. Three days later her body was found floating in the Snake Creek Canal about half a mile east of U.S. Route 27 in Miramar. There were no immediate signs of foul play, but investigators believed her death was caused by drowning and suspected homicide.

Her killing was later linked to a series of unsolved crimes known as the Flat-Tire Murders that occurred in Broward and Miami-Dade Counties from early 1975 into early 1976. The victims, primarily young white females, were often located in or near canals and many showed evidence of beating, sexual assault, or being stripped. The suspected offender was described as a white male in his early twenties, physically fit, well dressed, possibly married, and described as intellectually capable and sexually sadistic. No arrests were made and the case remains unsolved.
