LOWELL, MI -- Two men killed in a small plane crash in the Lowell area have been identified as residents of Northern Michigan.

The Thursday evening report said the circumstances causing the 1969 Cessna 172 to crash are still unknown. The FAA and the National Transportation Safety Board will further investigate.

The investigation of a two-vehicle crash between Harrison and Madison street led to the roadway being closed for five hours.

A Safford man and his three young children were among six people who died Wednesday night when their small plane crashed into a mountain east of Phoenix.
