·2 min read

Matthew Mindler's cause of death has been revealed about two months after the actor's death was ruled a suicide.

Mindler died of sodium nitrate toxicity, the Lancaster County Medical Examiner's Office confirmed to TMZ. He was 19.

The medical examiner's office did not immediately reply to PEOPLE's request for comment.

The former child actor, who appeared in the 2011 comedy Our Idiot Brother, intentionally ingested sodium nitrate, a preservative that can be fatal when ingested in high quantities.

Mindler's mom, Monica, told TMZ she did not know her son was suicidal, and that she was speaking out to warn others of the dangers of sodium nitrate and its potentially lethal uses. Matthew bought $15 worth of sodium nitrate on Amazon, Monica said, telling TMZ the dose was enough to kill four people.

Matthew was initially reported missing in late August after disappearing from his dorm at Millersville University campus in Pennsylvania, where he was a first-year student.
