A 73-year-old Cullman man convicted of capital murder has died in prison.

Doyle Lee Farr was serving life without the possibility of parole at William Donaldson Correctional Facility in western Jefferson County.

Farr died at the prison at 7:50 a.m. Sunday, according to the Jefferson County Coroner’s Office. He is believed to have died of natural causes.

Farr was one of two men convicted in the 1997 murder of 27-year-old Tammy Lynn Croft. He was convicted in 2000.

Investigators told The Cullman Times in 2013 that the victim was restrained by the men and that Farr removed her panties and forced them down her throat, causing her to asphyxiate.

“They wrapped her body in carpet and hid it in a neighbor’s barn,’’ Investigator Tim Creel told the publication. “The following day they removed it and put it in some brush on a county road where the body was found a few days later by people riding horses.”
