Gregory Malley Winkle was 16 when he was abducted and murdered on May 29, 1971, in Houston, Texas. Born January 24, 1955, in Alameda County, California, Gregory was taken while walking to a local swimming pool with a 13-year-old friend, David Hilligiest. The boys were lured into a white van and taken to an apartment rented by Dean Corll on West 11th Street, where they were abused and killed. Gregory’s cause of death was ruled asphyxia due to strangulation by the Harris County Medical Examiner’s Office.

Their remains were recovered in 1973 among many others in Corll’s boat shed at 4500 Silverbell Street. Corll’s crimes were exposed after an accomplice, Elmer Wayne Henley, fatally shot Corll; accomplices Henley and David Brooks were later arrested and convicted and received life sentences. If anyone knew Gregory, his movements that day, or has information related to his abduction, please share what is known.
