GILBOA - A Stevensville, Mich., man drowned while scuba diving in Gilboa Quarry on Sunday morning.
Benjamin Scott Hartman, 26, was part of a diving suit demonstration by San Diego, Ca.,-based diving suit manufacturer Diving Unlimited International, when he drowned at 10:13 a.m., the Putnam County Sheriff's Office reported. He was pronounced dead at St. Rita's Medical Center.
According to the report, divers were demonstrating the dry suits in groups that were supervised by certified instructors. Hartman was with a group of four other divers and an instructor when he went astray with another group doing a deep dive.
The report said Hartman's instructor went after him when he noticed Hartman descended into a deep portion of the quarry. The instructor stopped Hartman at 120 feet deep and began to assist him on his ascent to the surface, the sheriff's report said. During the ascent, Hartman allegedly panicked and lost his breathing regulator.
Once on the surface, the report said, other divers performed rescue breathing and cardiopulmonary resuscitation until rescue crews arrived. Hartman was flown by helicopter to St. Rita's.
Records at The Lima News show two other scuba divers died in Gilboa Quarry in the past six years. On June 9, 2002, 49-year-old James Colopy of Uniontown died of an embolism when he ascended too quickly from his dive. Brian Sedran, 34, of Windsor, Ontario, drowned on June 22, 1997. All three incidents occurred on Sundays.
