Former child star Matthew Mindler, 'Our Idiot Brother' actor, died by suicide, coroner says

Former child actor and "Our Idiot Brother" star Matthew Mindler's cause of death has been determined.

The 19 year old died by suicide, Eric Bieber from Lancaster County Coroner’s Office and Forensic Center confirmed to USA TODAY Thursday.

Mindler was enrolled in Millersville University in Pennsylvania, which reported him missing in late August after he didn't return to his room. Later that week, University president Daniel A. Wubah announced that Mindler had been found dead. Mindler's body was discovered in a wooded area near campus, according to university spokesperson Janet Kacskos.

"This is a time of grief for the family, our campus and the community," Wubah wrote in a letter on Twitter at the time. "I ask that the campus community come together to support each other, and our students, during this difficult time."

Mindler, from Hellertown, Pennsylvania, was a first-year student at the university. He was last seen walking from his dorm on Aug. 24. University police filed a missing adult report two days later after he didn't attend any of his classes for the rest of the week. More than 40 search and rescue team members were dispatched to find him, according to Kacskos.

Before attending the university, Mindler appeared in multiple TV shows and movies as a child actor, including "As the World Turns," "Late Show With David Letterman" and "Last Week Tonight With John Oliver."

In 2011, Mindler portrayed the role of River alongside Paul Rudd in the comedy "Our Idiot Brother." His most recent role was in 2016, according to IMDb, when he played the role of Peter in TV's "Chad: An American Boy."
