ARGYLE (CBS 11 NEWS) – Loved ones of 36-year-old Julio Ledesma gathered at Argyle High School for a Friday night vigil. They came together at the spot where he died near the baseball complex.

Ledesma was a construction worker helping to build a new indoor sporting complex at Argyle High School when the structure came crashing down on Thursday. Three others were hurt but are expected to recover.

Estrella Rodriguez, a family friend, said he was a devoted father of three and a hard worker.

Rodriguez said, “It was something that was unexpected because the last time that I saw him was the last day of his birthday.”

Loved ones lay flowers and lit candles as they prayed for the man.

Federal investigators from OSHA are still trying to determine what caused the structure to come down.
