SIOUX CITY | The Lyon County Sheriff said Friday the helicopter that crashed earlier in the week was from a Sioux Falls business and that the injuries to two people were not life-threatening.

Lyon County Sheriff Stewart Vander Stoep said the helicopter, piloted by Robert Krier, went down less than one mile southwest of West Lyon Community Schools outside Inwood, Iowa, after it struck an electrical wire Monday.

Vander Stoep said the pilot and another man had been searching the area for missing cattle, which were reported loose Monday.

Krier worked for Ride the Sky Helicopters and his passenger, Steve Ahrendt, were transported to Sioux Falls hospitals. The sheriff said Krier received head injuries and Ahrendt had broken ribs.

"They were not life-threatening injuries," Vander Stoep said.

Representatives of the Federal Aviation Administration are still investigating the incident to pinpoint a cause, including if any helicopter equipment malfunction took place.

Vander Stoep said helicopter crashes are rare in Lyon County. He estimated a prior  crash was about 20 years ago, when Vander Stoep was a deputy for the sheriff's office.
