MGN FORT LAUDERDALE, Fla. (AP) – South Florida detectives are investigating after a man died in a hospital less than a day after being arrested. The Broward Sheriff’s Office reports that deputies responded Wednesday evening to a possible gas station robbery near Fort Lauderdale. The deputies reported finding 26-year-old Markus Clark struggling with a clerk in an enclosed register area. After climbing through an opening in the protective enclosure, it reportedly took several deputies to get control of Clark, who authorities say appeared to be under the influence of an unknown narcotic. Officials say Clark was taken to a nearby hospital for medical evaluation. He was pronounced dead Thursday morning. The medical examiner’s office will conduct an autopsy to determine the cause of death.
