Alex Kintner was an Islander and the son of Mrs. Kintner. In Jaws, Alex Kintner is seen for a brief period enjoying a day at the beach on Amity. During Independence Day festivities, a calamity would occur that would result in the reported second shark attack on the island. This incident would set in motion a search for the shark responsible for the horrendous attacks that would plague Amity that summer. Alex was an avid swimmer, yet his choice to swim further out and separate from the rest of the swimmers would sadly prove catastrophic.
