Mark Steven Scott was 17 when he left his home in the Heights neighborhood of Houston on April 20, 1972, to spend time with friends and never returned. His parents soon received a postcard allegedly from Mark saying he had found work in Austin and would return after saving money for a lawyer; the family doubted the note’s authenticity.

Later investigations and confessions by Elmer Wayne Henley Jr. and David Owen Brooks place Mark among the victims of Dean Corll. Henley said he and Brooks lured Mark to Corll’s residence at 925 Schuler Street, where Mark was forced to write the postcard, raped and tortured, and then strangled to death by Henley the next morning. Henley and Brooks said they buried his body at High Island Beach in Galveston County, but the remains have never been recovered and the burial site was submerged after Hurricane Ike in 2008.

Mark Scott is the only confirmed Corll victim whose body has not been found. Does anyone have memories or information about Mark’s last known movements in Houston in April 1972?
