Marco Antonio Alaniz III was born on January 20, 2011, in Yuma, Arizona, and passed away on September 17, 2025, in Phoenix, Arizona. He was the beloved son of Marco Antonio Alaniz Ir. and Denise Gomez. Marco is survived by his two brothers, J. Alexander Silva and Davian Adriel Alaniz, as well as his cherished grandparents, Elvia Gomez and Marco A. Gomez, with whom he shared a deep and loving bond.

Affectionately known as "Marky," he was a freshman at Cibola High School. Marky had a vibrant personality and a wide range of interests.
He enjoyed riding his bike with friends, spending time with his girlfriend, and sharing laughter with his brothers through playful jokes and silliness. A lover of fashion and music, he was often found listening to his favorite songs or admiring classic cars and old-school tunes. Most of all, Marky valued time spent with his family, creating memories filled with love and joy.

Marky aspired to become a neurosurgeon —a dream that reflected both his intelligence and his ambition. He was a kind-hearted, enthusiastic, and thoughtful young man whose presence brought light and laughter wherever he went. He had a special gift for making others smile with his humor and warmth.

Marky's spirit, love, and joyful energy will be deeply missed by all who had the privilege of knowing him.
