Gary Sinise, aged 68, and his spouse, Moira Harris, aged 69, tragically endured the loss of their progeny to cancer on January 5, 2024. The seasoned CSI: NY alumnus chose Instagram as the platform to affirm this sorrowful occurrence on February 27, 2024. Gary opted to disseminate the statement’s link via social media, expounding on his son’s demise on the Gary Sinise Foundation’s website.
McCanna “Mac” Anthony Sinise, at the tender age of 33, succumbed to the ravages of cancer. In the lead-up to his demise, Gary’s son was immersed in crafting his musical opus. The foundation’s website conveyed, “The week the album went to press, Mac lost his battle with cancer,” elucidating that he passed away on January 5, 2024, at 3:25 pm, with his final resting place marked on January 23rd. Amidst the melancholic news of Mac’s departure, presented below are five illuminations about his persona.
Mac Sinise’s Struggle with Chordoma Through the conduit of Gary’s foundation website, the father of three unveiled that his progeny grappled with an uncommon variant of cancer since 2018. Gary inscribed, “Then, on August 8th, we found out that Mac was diagnosed with a very rare cancer called Chordoma.” The specifics of Chordoma, a bone cancer affecting the spine and skull, were unfamiliar to Gary until that moment, as articulated on the Mayo Clinic.
Mac underwent a series of surgeries in his battle against cancer during the years antedating his demise. Gary elucidated, “With Mac, after surgery to excise the initial tumor in September of 2018, and another spine procedure in February 2019 to eradicate what appeared to be an infection, regrettably, a follow-up scan in May of 2019 divulged the recurrence and spread of his Chordoma.” Post these events, Mac underwent additional surgeries, coupled with sessions of radiation and chemotherapy.
As revealed by the actor renowned for his portrayal in Forrest Gump, Mac possessed an ardent ardor for music. Despite grappling with cancer, Mac persisted in playing musical instruments and crafting his album in the months antecedent to his demise. Although paralyzed from the chest down, Gary shared that Mac exhibited mobility in his right arm and left hand. It was Moira, Mac’s mother, who proposed he learn the harmonica, given the inability to play drums. “He did, and it was beautiful,” expressed the proud father on the foundation’s website.
He Begets Two Siblings Beyond their departed son, Gary and Moira take pride in their two additional adult offspring. Sophie Sinise, their daughter born in 1988, precedes her sister, Ella Sinise, by approximately four years. Sophie, now 35, carves her path as an actress with credits in films like Swamp Shark (2011) and The Heart of Christmas. Ella also possesses an IMDb page, though devoid of listed projects.
Not only did Mac confront cancer in 2018, but his mother Moira, too, faced a similar diagnosis. Gary chronicled on the foundation’s website, “The summer of 2018 was a particularly challenging time for our family. In June of that year, my wife Moira was diagnosed with stage 3 breast cancer, and after surgery to excise lymph nodes, she embarked on a course of chemotherapy and radiation.” After months of treatment, the 69-year-old entered remission and has been free of cancer since.

I’m so sorry,” conveyed singer Katharine McPhee. Actor Michael Beach extended his sympathies, stating, “So sorry for you and the family.
