The Ascension Parish Sheriff’s Office is on the hunt for a man considered armed and dangerous who is accused of robbing a man during a gun sale.

The victim had made posts on social media sites advertising an AR-15 assault rifle he intended to sell, the Sheriff’s Office wrote in a news release.

A man who identified himself as Tyewayne Morris, 19, indicated interest in the gun, and the two men met Wednesday in a secluded area for a test fire. After firing one round, Morris turned the rifle on the seller and demanded his wallet, deputies wrote.

Morris let the victim leave but threatened to hurt him if he went to the authorities, the release states.

Deputies executed a search warrant at Morris’ home at 11451 La. 931. They found the rifle, but Morris wasn’t at home, according to the Sheriff’s Office.

Morris is described as a black male standing 5 feet 10 inches and weighing approximately 145 pounds. His criminal history includes simple battery, theft and illegal possession of stolen things, according to the Sheriff’s Office.

Authorities are asking anyone with information on Morris to call Crime Stoppers at (225) 344-7867.
