FORT PIERRE, S.D. (KELO) — Two people died in a house explosion southeast of Fort Pierre, according to authorities at the scene Wednesday afternoon.

KELOLAND’s Bob Mercer was also on the scene at the Antelope Creek area off of South Dakota 1806 Wednesday afternoon and saw at least one body being removed from what’s left of the home. Mercer reported the house is flattened and the explosion sent debris flying 50-to 100 yards in all directions.

The only thing left standing is some children’s playground equipment.

Stanley County Sheriff Brad Rathbun confirms one adult died in the explosion. The identity of the second person is unclear as of 3:15 p.m. Wednesday.

According to a GoFundMe set up for the family affected by the explosion, a third person has died, and two boys are hurt.

“One of the neighbors called it in,” Rathbun told KELOLAND News. He says people who lived in the area heard the blast around 10:20 a.m., which destroyed the home.

At this point, the cause is unknown.

“That’s why the fire marshals are here now,” Rathbun said.

Stanley County officials tell us the state fire marshals office is investigating along with the Division of Criminal Investigation.

Rathbun says authorities are not suspecting foul play but they are still looking into the cause.

The emergency response included help from a number of local agencies including Hughes, Hyde and Stanley Counties.
