Matthew Mindler died by suicide.
The former child actor - who was best known for starring opposite Paul Rudd in 'Our Idiot Brother' - was found dead earlier this week, after going missing from Millersville University in Pennsylvania.
And Lancaster County Coroner’s Office have now confirmed to TMZ that the actor's sad death has been ruled as a suicide, but there are still pending toxicology results on his body.
Matthew's tragic passing was confirmed by the university.
A message on Millersville University's Twitter page read at the time: "Dear Campus Community, 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. Our thoughts of comfort and peace are with his friends and family during this difficult time. A search had been underway for Matthew since Thursday, after he was reported missing. Millersville University Police and law enforcement agencies from the area had been searching for him since that time.
"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.
