An inmate of the Houston County jail died Saturday afternoon. According to Sheriff Lamar Glover, state troopers took 50-year-old Gary John Duffield into custody late last night for driving under the influence. Duffield refused his lunch at 11:30 today and was unresponsive when officers in the jail checked on him about one o'clock Saturday afternoon. Paramedics transported him to Southeast Alabama Medical Center where he was pronounced dead on arrival. An autopsy will be performed on Duffield Sunday, although no foul play is suspected.
