A suspect in a murder investigation out of St. Helena Parish was found Friday — dead from an apparent suicide, the State Fire Marshal’s Office has announced.

On Oct. 11, investigators found the “charred remains” of 39-year-old Marsha Allen inside a home on La. 1043 in Greensburg. According to her autopsy, she died hours before the fire, which was ruled an arson, the Marshal’s Office wrote in a news release.

Marsha Allen’s husband, Adren Allen, 48, was a suspect in both her death and the subsequent arson. Adren Allen said he left the home to purchase livestock feed before the fire broke out, but investigators placed him at the scene when the blaze began.

“As investigators turned their focus to (Adren) Allen early in the investigation, he disappeared from the area,” the release states.

On Friday, investigators got word that he had been hiding in a camp along the Amite River near Felixville.

When investigators went to Felixville to investigate the tip, they found Marsha Allen’s car in a wooded area close to the East Feliciana Parish and St. Helena Parish boundary line.

The State Fire Marshal’s Office said Adren Allen’s body was inside.

“Investigators believe (Adren) Allen took his own life,” the Marshal’s Office wrote.

St. Helena authorities have suspected that the fire was intentionally set since it occurred. But authorities provided few details about what made them suspicious or if they had any suspects.

State Fire Marshal’s Office investigators were assisted in the investigation by the St. Helena Parish Sheriff’s Office, the East Feliciana Parish Sheriff’s Office, the Livingston Parish Sheriff’s Office and the state Department of Wildlife and Fisheries.
