A month after formally pleading guilty to possession of child pornography, Glee actor Mark Salling has died of an apparent suicide, TMZ is reporting.

Salling, who played Puck on the popular musical comedy, was arrested in December 2015 and charged with possessing more than 50,000 images of child pornography. He pleaded guilty on September 30, 2017, agreeing to register as a sex offender and undergo treatment, among other stipulations. Salling's body was reportedly found in a riverbed near his home in Sunland, though the exact cause of death hasn't been released.

"I can confirm that Mark Salling passed away early this morning," an attorney for the actor said in a statement. "Mark was a gentle and loving person, a person of great creativity, who was doing his best to atone for some serious mistakes and errors of judgment."

The 35-year-old actor was due back in court to face sentencing, when he was expected to receive four to seven years in prison as part of a plea deal. TMZ reported the actor previously tried to take his life in August 2017 by cutting his wrists.

His tragic end is at least the second death from the Glee cast: Star Cory Monteith, who played Finn Hudson, died of an accidental drug overdose in 2013 at age 31.
