Rest in peace, Houston Tumlin. The former child actor died by suicide on Tuesday, according to multiple reports. He was 28.

The movie -- which also starred John C. Reilly, Sacha Baron Cohen, Jane Lynch, Andy Richter, Molly Shannon and Amy Adams -- is Tumlin's only acting credit. Tumlin reportedly went on to serve in the Army's 101st Airborne Division at Fort Campbell. 

In addition to various news reports, Tumlin's girlfriend, Charity Robertson, also confirmed his death in a Facebook post.

"I’ll miss your big heart, caring spirit, infectious laughter, and oh man could the list go on," she wrote. "I love you so much Houston Lee and thank you for loving me so passionately and unapologetically for the time we had each other."
