Billy O'Neil Killian

Billy O’Neil Killian, age 38, passed away unexpectedly from complications of an asthma attack. He was a devoted husband to Danielle Lynne and a proud father to Gabriella Damiana and Bryce Joshua. His family was his world—he lived by the motto “Family over Everything.”

He is survived by his loving parents, Bill and Shauna Killian and his brother, Connor; his grandmother, Diane LaPosta. He was preceded in death by his best friend and brother, Joshua Michael, his grandfather, Dick LaPosta, and his grandmother, Sheila Killian. He also leaves behind many cherished nephews, cousins, aunts, uncles, and friends who will forever hold him in their hearts.

A true Gator fan and loyal supporter of the Dolphins, Billy brought joy and laughter to every game day. His love for life was matched only by his love for his family. To Danielle, he was not just a husband, but her soulmate—always calling her “my love, mi amor.”

Billy will be remembered for his kindness, his unwavering loyalty, and the way he made everyone feel like family. His legacy lives on in the hearts of those who knew him best.

In lieu of flowers, the family kindly asks that you consider offering a prayer for Danielle, Gabriella, Bryce, and the entire Killian family, or, if you wish, a contribution to the GoFundMe account created in Billy’s memory.
