In January, Gary Sinise lost his son, McCanna “Mac” Sinise, to cancer.

He was 33 years old. Now, the Forrest Gump star shares tear-jerking details about his son’s final days in life.

Gary Sinise, who has helped so many veterans regain harmony in their lives, truly deserves to live in peace and joy.

However, the acclaimed actor has recently endured profound personal pain.

The very last moments

Two months ago, we were hit by the heartbreaking news of McCanna “Mac” Sinise’s passing, after many years battling cancer.

But it is only now that his father, Gary Sinise, is opening up in detail about his son’s final days. In an interview with ET, Gary shares how his son gracefully navigated through the last difficult moments of his life.

To start with, Gary revealed that his son actually completed a music album he had been working on for the past few years. “I bought him his first drum set when he was 9 years old,” Gary recalled in a conversation with ET.

Talented musician

”He played through high school, and then he went to USC Thornton School of Music. He was playing drums all through college and studying songwriting and composition. He created a bunch of pieces of music while he was at college.”

But during the last years of his life, Mac just put them away and didn’t do anything with them. In January 2023, he said, ”Dad, I think I want to try to finish this music that I worked on all those years ago in college.”

Just like his father, Mac was a very skilled and talented musician. He learned to play the harmonica while undergoing cancer treatment. Mac recorded the final parts of his album during his last week in life, and his album is currently being finalized. It will be available for purchase on the Gary Sinise Foundation website. Additionally, it will be streamable for those who wish to listen to it.

Last days of his life

Gary reminisces about the day when Mac had a viewing party. Sadly, it would become a kind of farewell.

”It was a joyful day. The following night, I went on television and talked about Mac. Then the next day, I had to call the ambulance and take him to the hospital,” Gary shares.

But Mac needing to go to the hospital was quite common. He would often spend a few days there, stabilize, and then be able to come home. The family thought that would be the case on this day as well – but they were mistaken. At the hospital, doctors realized the situation was extremely serious, and soon it dawned on the Sinise family that Mac was probably in his last days of life.

Many might think that everything was pitch black in this situation – but Gary points out that Mac found peace in knowing he had done everything he wanted in life.

Sure, there were dark moments, but Mac was a true fighter all the way.

”He was at peace. He was happy at the end of his life. He was joyful… He was smiling,” Gary says.
