HINTON, Iowa — Two people were critically injured in a northwest Iowa grain elevator explosion.
The explosion occurred just after 1 p.m. Thursday, March 17, 2016, at Central Valley Ag in Hinton, according to a statement from the Iowa Department of Public Safety.
Plymouth County Sheriff Mike Van Otterloo said two people were taken to a Sioux City hospital in serious condition.
Authorities identified the victims Monday, March 21, 2016, as 28-year-old Shane Noreen and 24-year-old Gustavo Gutierrez. Both were transported to Omaha hospitals where they were reportedly in critical condition.
U.S. Highway 75 and a county road were closed through Hinton to allow emergency crews to quickly reach the grain elevator, but the roads were later reopened.
Authorities had asked that trains not travel through the area but rails also were reopened.
The cause of the explosion remained under investigation as of Monday, March 21.
