Salling's lawyer, Michael J Proctor, tells The Associated Press the actor died today. His death comes weeks before the actor was scheduled to be sentenced in federal court on child pornography charges.
Proctor did not reveal the cause of death.
Salling pleaded guilty in December to possession of child pornography. Prosecutors say a search of Salling's computer found more than 50,000 images of child porn on Salling's computer and a thumb drive.
He was scheduled to be sentenced March 7.
He played bad-boy Noah "Puck" Puckerman on the long- running show, which concluded in 2015.
