Marcus Daniel Jentsch, 18, Schiller Park, IL. Passed away Saturday, August 15, 2026. Loving Son of Patrick Jentsch and Miriam Mendez. Beloved Brother of Raymond, Siobhan, Olivia, Sean and Emilia. Amazing Nephew of many loving aunts and uncles. Cherished Cousin and Great friend to many.

Marcus recently graduated in May from East Leyden High School where he also played for the football team. He had a vibrant spirit that was surely felt and he shined with optimism. There was a better feeling to life when he was around. As we’ll all be broken-hearted forever, we’ll hold on tightly to the abundance of his love that he brought to us all.
