McCanna “Mac” Anthony Sinise, the musician son of actor Gary Sinise, died of the rare spinal cancer Chordoma. Mac Sinise, who had recently completed work on his album Resurrection & Revival, died on January 5 following a years-long battle with the disease. Gary announced his death yesterday on the Gary Sinise Foundation’s website. He wrote: “The week the album went to press, Mac lost his battle with cancer. He died on January 5, 2024 at 3:25pm, and was laid to rest on January 23rd. Like any family experiencing such a loss, we are heartbroken and have been managing as best we can…I am so blessed, fortunate, and proud to be his dad.” Mac Sinise was diagnosed with Chordoma in August 2018, just two months after Gary Sinise’s wife Moira was diagnosed with stage 3 breast cancer. Chordoma affects, on average, only 300 people in the U.S. per year. Mac Sinise also served as drummer in Gary’s band the Lt. Dan Band.
