Lawsuit filed over Oklahoma gas rig explosion that killed Colorado man, 4 others

McALESTER, Okla. — A wrongful death lawsuit has been filed over a natural gas rig explosion in southeastern Oklahoma that killed five men — three from Oklahoma, one from Texas and one from Colorado.

The lawsuit by Dianna Waldridge, the widow of 60-year-old Parker Waldridge of Crescent, alleges negligence by Red Mountain Energy and Red Mountain Operating, both of Oklahoma City, and Patterson-UTI Drilling and Patterson-UTI Energy, both of Houston.

Patterson-UTI declined comment in a statement, saying it’s committed to preventing future such accidents.

Red Mountain president Tony Say referred questions to his attorney, who did not immediately return a phone call for comment.

The Jan. 23 explosion near Quinton killed Waldridge, Matt Smith of McAlester, and Roger Cunningham of Seminole; Josh Ray of Fort Worth, Texas; and Cody Risk of Wellington.
