Shelle McGugin, 35, was found dead in her Sunflower Apartments unit on Northeast Loop 410 in San Antonio on June 2, 1999. Her body was decomposed and the Bexar County Medical Examiner’s Office ruled the cause of death strangulation with an electrical cord. Investigators noted she had been dead several days before being discovered, which made establishing a precise timeline difficult.

The San Antonio Police Department’s investigation did not immediately produce suspects or arrests, and the homicide remained unsolved. The cold case division has continued to seek information that might identify who was responsible. If anyone knew Shelle, lived near the Sunflower Apartments in 1999, or has information that could help, contact the San Antonio Police Department.
