Former child actor Benji Gregory, best known as ALF's Brian Tanner, has died, his sister confirmed in a social media post.
The car was discovered June 13 in a bank parking lot in Peoria, Ariz.
"We believe he went there the evening of the 12th to deposit some residuals," Hertzberg-Pfaffinger wrote in her post. "...and never got out of the car to do so. He fell asleep and died from vehicular heatstroke."
That day, the temperature peaked around 109 degrees, People reports.
ALF, which ran on NBC from 1986 to 1990, chronicles the doings of ALF, a Melmac alien named Gordon Shumway, who crash-lands into an American family's garage.In addition to Gregory, the show starred Paul Fusco, Max Wright, Anne Schedeen and Andrea Elson.
As an actor, Gregory also appeared in shows like Punky Brewster and movies like Jumping' Jack Flash. Variety said he also served in the U.S. Navy.
She told various outlets that her brother had been living with depression and bipolar disorder and often had trouble sleeping.
