The deputy mayor of Chatres, France identified a 29-year-old as one of the Paris terror attack gunmen.

Jean-Pierre Gorges says that Omar Ismail Mostefai was one of the gunmen in the attacks, which left over 100 people dead and hundreds of others wounded.

Mostefai lived in Chartres, which is about 100 miles (90 kilometers) southwest of Paris, until 2012.

Mostefai is the first, and so far the only, attacker to be named by police. His brother, father, and sister-in-law have been brought in for questioning by French police.

But his brother, 34, told AFP that he had not seen Mostefai for several years, with his whereabouts unclear after he moved from Chartres.
