Howard Vaughn Gratteau, a 39-year-old air conditioning repairman from Davie, Florida, disappeared on September 1, 1986. He was last seen by his wife and stepdaughter at about 7:30 a.m. leaving home in the 6600 block of southwest 41st Street to do a repair in the Honey Lakes subdivision and was expected back within an hour for a planned family sailing trip.

Gratteau was diabetic and had taken his morning insulin but left without extra medication, raising the risk of insulin shock if he became delayed. His white 1985 Toyota pickup with a camper top and a B&H Air Conditioning logo, bearing a novelty Florida plate reading HOWARD2, also vanished. Accounts were left untouched and extensive ground and aerial searches, with attention to waterways and canals, turned up no trace and no credible leads emerged.

Family members have suggested a medical emergency leading to an accident, but the case remains unsolved. If anyone knew Howard, his truck, or saw him in Davie or the Honey Lakes area on September 1, 1986, please share what you know.
