FINNEY COUNTY, Kan. -

A teenager has died and two others are hospitalized after a home explosion in Finney county.

It happened in Plymell, Kan. near Garden City, about a quarter mile east of Highway 83 5:30 p.m. Saturday. Kevin Bascue, Finney County Sheriff, said the blast could be heard at least 10 miles away.

Lawrence Bustamante, nearby neighbor, said the blast was so powerful it shook the ground. 

"I was sitting back here when all of a sudden I heard 'boom.' Debris was raining down and in an instant the house was flattened," Bustamante said. 

Emergency crews arrived to find the home leveled. The blast also damaged a nearby home, Bascue said.

"I don't know what happened over there. All I know is I was sitting down then I heard the loudest noise of my life. I looked over there and it was bad," Bustamante said.

Spencer Unruh, 17, died in the blast. His mother, Kelly Unruh, and a 14-year-old brother, Riley Unruh, were flown to Wichita for treatment.

Both remain in critical condition.

Chief Allen Shelton, Garden City Fire Department, said the cause of the explosion was due to a concentration of gas. It is being investigated as an accident.

A spokesman for Midwest Energy said the company is working with investigators in the case.

A fund has been set up to help the family with funeral and medical expenses. Click here to learn more.
