Trevor Moore, a founder of the Whitest Kids U Know sketch comedy group, passed away on Friday night in an unspecified accident. He was 41 years-old.

A statement on the behalf of Moore’s family was released to Deadline by Moore’s family.

“We are devastated by the loss of my husband, best friend and the father of our son,” the statement read. “He was known as a writer and comedian to millions, and yet to us he was simply the center of our whole world. We don’t know how we’ll go on without him, but we’re thankful for the memories we do have that will stay with us forever.”

“We appreciate the outpouring of love and support we have received from everyone,” the statement added. “This is a tragic and sudden loss and we ask that you please respect our privacy during this time of grieving.”

Moore launched Whitest Kids U Know back in 1999 with Zach Cregger and Sam Brown at the School of Visual Arts in New York City. Timmy Williams and Darren Trumeter would later join the group, which is still active to this day.

“There isn’t really anything I can say that will cover the place he had in my life. He was a one of a kind. A brilliant and kind man. I’ll miss you forever buddy,” Cregger tweeted, with Brown adding, “Making @itrevormoore really laugh always gave me a sense of accomplishment.  I’m so lucky I got to spend the last 20 years trying to get good at that.”

Cregger and Brown also released a joint statement on the website of their upcoming movie, Mars.

“Early this morning, we learned that we lost our brother, our collaborator and the driving force behind WKUK,” read the message. “He was our best friend, and we speak for all of us in saying that the loss of Trevor is unimaginable. We are heartbroken and our grief pales in comparison to the loss felt by his wife and son.”

“On behalf of WKUK, we ask for privacy during our time of profound grief, and strength for his family who are dealing with the impossible thought of living life without him,” they added. “Our hope is that friends, fellow artists, and fans that loved him will not focus on his death, but will remember the countless moments of laughter he gave them.”

Moore is survived by his wife Aimee Carlson, and their son, August.
