Matthew Mindler has been found dead at the age of 19 - three days after he was reported missing.
The former child star was perhaps best known for his role in the 2011 comedy movie Our Idiot Brother, in which he played River Byng alongside Hollywood stars such as Paul Rudd and Elizabeth Banks..
As reported by Page Six, the news was delivered by the Millersville University student body on Saturday. Mindler had been a freshman at the university.
The announcement read: "It is with a grieving heart that I let you know of the death of 19-year-old Matthew Mindler from Hellertown, Pennsylvania, a first-year student at Millersville University. A search had been underway for Matthew since Thursday, after he was reported missing."
It continued: "Matthew was found deceased this morning, Saturday, August 28, in Manor Township near campus. Matthew was transported to the Lancaster County Forensic Center by the coroner for further investigation."
Page Six adds that Mindler's cause of death has not yet been revealed.
The publication adds that Mindler's concerned family filed a missing persons report earlier in the week, after the teenager failed to "return to his room or return phone calls from his family" on Wednesday.
The student was last seen leaving his dorm building at approximately 8:00PM on Tuesday. Mindler did not show up for any of his classes the following day.
As well as Our Idiot Brother, the actor's IMDb page states that Moindler also starred in the 2016 TV movie Chad: An American Boy.
Our thoughts are with Mindler's family and friends at this time.
