MIDLAND, Texas, March 11 (UPI) -- Three members of the same family were killed Tuesday after an oil rig exploded in Upton County in west Texas.
The men, Arturo Martinez Sr., Arturo Martinez Jr. and Rojelio Salgado, were working for Mason, a pulling unit company contracted by Parsley Energy, about 40 miles south of Midland, Texas, when the oil rig exploded.
All three men died and a fourth was injured.
The Occupational Safety and Health Administration was on the scene to investigate the cause of the incident.
"Right now everything is in the preliminary stages. We don't know exactly what happened. We don't know what caused the explosion," Dusty Kilgore, investigator with the Upton County Sheriff's Office, told KWES-TV, Midland.
Arturo Martinez Sr. and Arturo Martinez Jr. were father and son, and Salgado was married to the elder Martinez's daughter.
"They were energetic real fun, my brother in law, he was always with his grand kids, he has five grand kids, three daughters, his wife. Big family, we were all one big loving family," Victoria Garcia, a family member, told KOSA-TV, Odessa, Texas. "We want answers, but of course we know that there has to be an investigation."
