Actor Gary Sinise Mourns His Son Mac, Gone at 33 — A Touching Story of Strength, Family, and the Legacy He Leaves Behind

The man who has spent decades comforting grieving families is now walking through a grief so deep it has shaken him to his core.

Gary Sinise — the beloved actor immortalized as “Lieutenant Dan” in Forrest Gump, and one of America’s most respected humanitarians — has revealed the heartbreaking news that his 33-year-old.
