Benji Gregory, the child actor who starred in the 1980s sitcom “ALF,” has died at the age of 46, according to his sister.

Gregory was found dead, along with his service dog, in his car on June 13, his sister Rebecca Hertzberg-Pfaffinger wrote on Facebook.

His vehicle was in a bank parking lot in Peoria, Arizona, The New York Times reported. Hertzberg-Pfaffinger said the family believes he went there the evening of June 12 to deposit some residual checks found in his vehicle, but “never got out of the car to do so.”

“He fell asleep and died from vehicular heatstroke,” she wrote.

At the time, Arizona was in the midst of a heat wave, with a high of 108 recorded June 12 and 111 recorded June 13, according to AccuWeather.

“Ben was a great Son, Brother and Uncle. He was fun to be around and made us laugh quite often. Still, going through his things, I find myself laughing at little videos or notes of his, in between crying,” his sister wrote.
