The sad news of Keenan Cahill’s passing is not an exception to how devastating it is when young people pass away too soon.

The popular YouTuber quickly gained social media fame in 2010 with his hilarious lip-syncing videos.

He tragically died on December 29, 2022.

Even though I don’t come from the younger generation that spends their days on YouTube, I still remember the first time I discovered Keenan Cahill there.

When you saw the young boy performing the day’s top hits, you couldn’t help but smile because of his charisma and contagious joy.

In 2010, Keenan’s first lipsynced YouTube performance of Katy Perry’s “Teenage Dream, was made available. Soon after, his videos started going viral, making him famous worldwide.

In 1995, Maroteaux-Lamy syndrome was discovered in Keenan Cahill, an infant born in Elmhurst, Illinois.

Patients with MPS typically have no symptoms at birth, but the uncommon genetic disease eventually causes many tissues and organs to grow and scar. Keenan underwent a bone marrow transplant in 1997 to stop the disease’s progression, but he would continue to live with it for the rest of his life.

In addition to weekly infusions, Keenan received “enzyme replacement therapy” when MedpageToday spoke with him in 2011. The native of Illinois underwent several operations over the years, including one to relieve cerebral pressure.

On December 15, Cahill underwent open heart surgery at a hospital in the Chicago area, but regrettably, there were complications.

His management asserts that even though he was put on life support, medical professionals could not save his life. He was 27.

Even though it had been a while since his big break, Keenan continued to have a sizable social media following.

On June 3, 2013, in New York City, YouTube sensation Keenan Cahill visited the SiriusXM studios.

He recently shared information about his most recent project, on which he worked with Jillian Jensen, also known as “Rain,” an artist. In one of his final updates in December, he provided a health update to his Instagram followers.

Open heart surgery will be performed in one week—best wishes to me. I adore you guys,” he wrote.
