SAUK RAPIDS, Minn. (AP) – Authorities are still working on identifying at least one of two victims of a small plane crash in Sauk Rapids.

The St. Cloud Times reports one victim has been preliminarily identified, but officials aren’t going to release that information until the IDs of both victims are known.

The Star Tribune says a National Transportation Safety Board investigator arrived at the damaged house owned by Jeff Hille on Saturday afternoon. Hille, a teacher at Sauk Rapids-Rice High School, said Friday night that his brother-in-law, Kole Heckendorf, was in an upstairs bedroom when he heard an explosion, saw flames and smoke, and jumped out a second-story window. Heckendorf was not injured. The NTSB is continuing to investigate the crash. 

The Brumwell RV-6 experimental airplane crashed into a house after it flew near an Allegiant Air flight from Mesa, Arizona.

The NTSB tells the Star Tribune that authorities will look into whether the second aircraft may have played a role.

Allegiant officials are cooperating with the NTSB.
