SAN ANGELO, Texas – After almost 30 years of searching, the Texas Department of Public Safety is looking for information surrounding the deaths of a couple in San Angelo.

In July 1988, Shane Stewart and Sally McNelly traveled to Lake Nasworthy, in San Angelo, to watch a fireworks display. The next morning, a lake ranger discovered Stewart’s abandoned 1980 Chevrolet Camaro parked several miles near O.C. Fisher Reservoir.

The couple's bodies were later found in that November near the Twin Buttes Reservoir. Autopsies revealed both victims had been shot dead.

The Texas Ranger Unsolved Crimes Investigation Team was created to assist Texas law enforcement agencies investigating unsolved murders or what appear to be serial or linked criminal transactions.

As part of a DPS public awareness program, one unsolved case is featured by the Texas Ranger Unsolved Crimes Investigation Team each month in an effort to generate new investigative leads and bring added attention to cold cases across the state.

San Angelo Crime Stoppers is offering a reward for information leading to the arrest of the person or persons responsible for the deaths of Stewart and McNelly.

Anyone with information is asked to call San Angelo Crime Stoppers at 1-800-756-3434.
