Cheryl Martin, 33, was found dead on November 3, 1989, in a drainage ditch in the 1800 block of FM 646 West in League City, Texas. She had been strangled and sexually assaulted; her body was estimated to have been deceased for one to two days before lawn crews discovered it. Cheryl was newlywed at the time and had worked as a prostitute at truck stops.

Her death is commonly included among the cases linked to the Texas Killing Fields murders. The case grew cold and has been described as having received little media attention, sometimes calling Cheryl the forgotten victim. League City Police have continued to keep the investigation open. Advances in DNA testing led detectives to re-examine evidence and they report believing they may have identified the murder weapon used to strangle Cheryl.

Anyone with information about Cheryl, her last movements, or the area around FM 646 West is asked to contact the League City Police Department.
