LAFAYETTE — The Lafayette Parish Sheriff’s Office has arrested four people accused of helping escaped inmate Marcus Dupuis avoid being captured, according to a news release.

Dupuis, 18, has been on the loose since Sept. 15 when he walked away from the Lafayette Parish Sheriff’s Office minimal-security work-release facility.

Dupuis was serving a five-year sentence for a marijuana possession conviction and had been in custody for six months, the Sheriff’s Office has said.

On Friday, the Sheriff’s Office announced the arrests of Dupuis’ girlfriend, Mollie Louise Smith, 18, and his mother, Andree Schelde, 49, both of Lafayette.

On Thursday, the Sheriff’s Office announced the arrests of two of Dupuis’ friends, William Berchtold and Mason Langlois, both 19 and from Lafayette.

All four were arrested on counts of accessory after the fact to simple escape, the release said.

Investigators met with Smith and Schelde on Sept. 15 to make them aware that Dupuis was wanted and that simple escape is a continual offense, meaning they could be charged with accessory after the fact if they provided him with transportation, lodging or financial assistance, according to an arrest affidavit.

On Sept. 24, Smith accompanied Dupuis to a party and did not inform authorities, the release said.

Afterward, Schelde gave Smith some women’s clothing, makeup and money for Dupuis “so that he could dress up as a female to move freely throughout the city without being recognized,” the release says.

Schelde is also accused of meeting with Dupuis on at least one occasion after she was told of his escape, the release says.

The release did not specify what roles Berchtold and Langlois played.

The Sheriff’s Office has limited releasing information because of concerns that Dupuis will learn of their efforts to locate him.

Investigators are in contact with other law-enforcement agencies, as Dupuis is believed to have fled the state, the Sheriff’s Office said.

Dupuis is described as a white man, 5 feet, 4 inches tall, 115 pounds with brown hair and brown eyes.

Anyone with information on his whereabouts is asked to call Crime Stoppers at (337) 232-TIPS.
