With heavy hearts, we announce the unexpected passing of David Casillas Jr, 27, of Rialto, California, on January 23, 2026.
David was a beloved son, brother, fiancé, and friend whose presence brought warmth, laughter, and love to everyone who knew him. He had a generous heart, a genuine spirit, and a way of making people feel seen and cared for. Whether through his kindness, his sense of humor, or simply showing up for the people he loved, David left a lasting mark on those around him.
Family meant everything to him. He shared a deep bond with his parents and siblings and was excitedly building a future with his fiancée, dreaming of the life they would share together. His love was steady and sincere, and his absence leaves a space that cannot be filled.
David is survived by his parents, David Sr and Manuela; his fiancée, Kiara; his sisters; and many extended family members and close friends who will forever carry his memory in their hearts.
Though his life was far too short, the love he gave and the memories he created will live on. He will be deeply missed and remembered always.
Arrangements are under the care of Forest Lawn, Covina Hills, CA.
