Cameron County Constable Precinct One Horacio Zamora reports a body washed ashore Sunday morning.
Constable Zamora said it all happened a mile and a half north of Beach Access Six on South Padre Island.
The body is believed to be that of missing 12-year-old Cummings Middle School student Daniel Bolado.
Daniel, his 18-year-old brother Jose Jesus Bolado and their cousin Ivan Roberto Bolado all went swimming near the jetties on South Padre Island's Isla Blanca park on Wednesday evening.
Investigators said 22-year-old Ivan was pulled from the jetties Wednesday night and flown to the Valley Baptist Medical Center in Harlingen.
There he was later pronounced dead.
The body of the 18-year-old Jose Jesus, a Porter High School student, was discovered at Boca Chica Beach on Friday.
