DETROIT -

Crime Stoppers is offering a $2,500 reward for information that helps close the case of a 70-year-old Wayne man's murder.

Nathan Mitchell was found dead Jan. 17 by officers who were sent to check on him in the 35000 block of Glenwood Road.

Mitchell lived next to the William C. Franks Furniture Store that exploded in 2010 due to a gas leak. After the explosion, Mitchell ran to what was left of the furniture store and did what he could to put out the flames that were burning the legs of Paul Franks, owner of the store who was still trapped under the rubble. He was the one holding Franks' hand while he was fighting for his life. Firefighters were able to free Franks.

Mitchell was retired from Ford Motor Company as an assembly line worker and was a Vietnam veteran.
