DNA testing has confirmed that a bone fragment recovered in the waters off Ali'i Drive is that of missing spearfisherman Paolo Dominici, 49, of San Francisco, according to Hawai'i County police.

Dominici, owner of Bacco Ristorante in Noe Valley, went spearfishing with a friend offshore of the Kona Makai Condominiums on the morning of April 11 and was reported missing after failing to return to shore. Fire department personnel found the bone fragment and other items belonging to the man, indicating he may have been run over by a boat.

Police said witnesses reported seeing a boat in the area where Dominici was believed to have been diving.
