Authorities say propane gas caused the explosion at a house west of Laramie that burned two people, later resulting in a man's death.

The Laramie Boomerang reports the Albany County Sheriff's Office has completed its investigation into the explosion and subsequent fire at the home near Sheep Mountain in late July.

The explosion injured Kimberly Brizuela and Scott Tiernan, who later died at a Greely hospital.

Undersheriff Josh DeBree says propane gas was responsible, but additional findings will be up to the Wyoming State Fire Marshal's Office. He says there was no evidence indicating a methamphetamine lab at the site, which was rumored by area residents. The state investigation is ongoing.


======================

William Scott Tiernan, who grew up in Delray Beach, died July 27 in Laramie, Wyo. He was 67.
Mr. Tiernan — who went by “Grand Dude” when with his grandchildren and by “Wild Bill” when on his Wyoming ranch — was born in West Orange, N.J., on May 18, 1951. The second of four kids, he grew up on the ocean in Delray Beach and spent his childhood summers surfing on Cape Cod and in East Hampton. 

He attended high school at Avon Old Farms in Connecticut, where he lettered in football, wrestling and lacrosse. After graduation, he served on the school’s board and donated a wrestling room in honor of his late father, John W. Tiernan.


After a series of adventures and surf trips around the world, Mr. Tiernan moved to Gulf Stream — just down the road from the home he grew up in — where he became a partner in the real estate brokerage firm Allmon, Tiernan & Ely. He also served on the board of his family’s company, Mark, Fore & Strike. After his retirement, he bought a property just outside Laramie, where he built a ranch and enjoyed making huge metal sculptures — much to his kids’ and grandkids’ delight.
