Rogelio Realme Cerda was 15 when he disappeared from Matagorda Beach, near Bay City, Texas, on June 29, 1975. He was on a fishing trip and went swimming with friends; an undertow swept him offshore along with two girls who were rescued. An extensive search turned up no trace of Rogelio, and authorities initially concluded he drowned.

Family members have questioned that finding, saying he was a good swimmer and pointing to reported strange phone calls and reported sightings after his disappearance that led them to suspect he might have survived or run away. Family tensions, including a difficult relationship with his father, have been mentioned as possible factors; his father died by suicide about a year and a half later. The case remains unsolved and is listed with NamUs and the Texas Department of Public Safety.

Did anyone in the Bay City or Matagorda Beach area in 1975 have contact with Rogelio or recall the reports of calls and sightings afterward?
