As if that wasn’t bad enough for Kathleen, to experience the love of her life being taken from her so soon, she suddenly passed away just four short years later. Just as her brother Joseph Jr. did, she too died in a plane crash. She boarded the aircraft expecting a pleasant holiday with friends in France, when the ride ended tragically. The plane lost control in the midst of a storm and the passenger’s last minutes were filled with terror as it bounced around dropping thousands of feet in seconds. When the plane finally made impact all four were killed instantly. Surprisingly, her father was the only one to attend her funeral.
