EL PASO, Texas -- The work has come to a stop at this arroyo repair project, a short distance from the intersection of Mesa Street and Paragon. Heavy machinery, now sitting idle, possibly cost one man his life.

"Firefighters arrived. They found a 26-year-old male unconscious. He was unresponsive. They initiated CPR and resuscitation measures. They transported him to a hospital," said Lt. Mario Hernandez with the El Paso Fire Department.

It happened just before 2 p.m. Monday afternoon. According to authorities, the accident involved a man working for Tapia Construction, one of the subcontractors doing concrete work at the site. Despite efforts made at the hospital, they were unable to save him.

"Unfortunately, the 26-year-old male was unable... he didn't make it. He was pronounced dead at the hospital," said Hernandez.

Authorities suspect that the man may have been run over by a bulldozer.

"Apparently, he died of massive internal injuries. The type of injuries that you would find when in a crushing accident," said Hernandez.

Throughout the afternoon, El Paso police interviewed co-workers, trying to determine the circumstances behind the incident. Late Monday, the contractor for the project released this statement:

"C.F. Jordan is conducting our own investigation and our thoughts and prayers are with the family at this time."

Others will also soon join in the investigation.

"We do have several industrial accidents which are investigated by O.S.H.A., but very few fatalities like this one," said Hernandez.

O.S.H.A., or Occupational Safety and Health Administration, investigates all workplace accidents. Work at the construction site remains shut down until further notice.
