A 4-year-old tragically passed away in a freak accident earlier this year... now his family has filed a wrongful death lawsuit. Life changed forever for the Kerr family in June when father Cathal and his two sons Charlie, 7, and Ronan, 4, went to play at the Villa La Jolla Park in San Diego. Unbeknownst to Cathal and Charlie, that would be the last time they ever got to go to a park with little Ronan.
