A Norwalk convicted felon was sentenced to four years in federal prison after he was found with an illegal gun, the United States Attorney for the District of Connecticut said Tuesday.

Christoper Miles left his loaded Glock 9 mm pistol inside the public restroom of a Norwalk restaurant in September 2023.

An employee found the gun and the manager contacted police.

Surveillance video showed Miles entered the restaurant before the weapon was discovered. The video also showed that he returned to the establishment twice and attempted to retrieve the gun.

Miles' DNA was found on the firearm.

Officials say Miles' criminal history included state convictions for assault, possession with intent to distribute narcotics and sale of a narcotic substance. Due to that history, Miles was prohibited from having a firearm or ammunition.

In February, a federal jury found him guilty of unlawful possession of a firearm by a felon.
