Two plane crashes occurring within a few hours of each other in and near Minnesota have left seven people dead, the Star Tribune reports.

Four people died around 5:20 p.m. last night, 50 miles from the Minnesota border in Alden Township, Wis., according to the Star Tribune. Hours later, three people were killed during the second wreck near Holland, Minn. shortly after 8:00 p.m.

Holland resident Travis Jasper told KSYF he heard the heard the plane’s engine sputtering before the crash.

“I thought I heard a car door slam and a couple minutes later I saw the neighbor at the corner and he said, ‘I think a plane just went down,’,” Jasper said, adding that he gave an emergency responder a ride on his dirt  bike to the site of the crash.

The first plane crash in Wisconsin also set fire to the cornfield it landed in, Minnesota Public Radio reported.

Authorities have yet to identify the seven people killed in either crash, according to the Star Tribune.
