An investigation is underway after the body of the son of a well known, deceased Atlanta bagpipe performer was discovered in the family home treehouse. Seventy-four-year-old Henry Frantz Jr. died in a scuba diving accident in Hawaii earlier this month. As family members were settling his home affairs, Frantz daughter discovered the remains of her brother, 28-year-old Hank Frantz, who has been missing for four years. WSB is reporting that the medical examiner's office says that the amount is decomposition suggests the younger Frantz may have died only a few months ago.
