Gregory, 46, died from heat exposure complicated by liver cirrhosis in his car in Peoria, Arizona.

Benji Gregory, known for his role as Brian Tanner on 'ALF,' was found dead in his car on June 13.
The Maricopa County Medical Examiner ruled his death an accident due to environmental heat exposure and hepatic cirrhosis.
Temperatures in Peoria reached 109 degrees on the day of his death, contributing to fatal heatstroke.
Gregory's sister revealed he suffered from depression, bipolar disorder, and a sleep disorder, which may have led him to fall asleep in his car.
