"Twilight" actor Gregory Tyree Boyce and his girlfriend, Natalie Adepoju, 27, were found dead at his home in Las Vegas.
The 30-year-old, who played high school student Tyler Crowley in the 2008 movie, was supposed to be in Los Angeles last week, visiting his daughter.
A cousin who was asleep inside the home woke up and noticed the actor's car was still parked outside. He went to check on Boyce and discovered the bodies.
TMZ reports white powder was found in the home.
The cause of deaths are pending and a police investigation is ongoing.
The late actor's mother, Lisa Wayne, took to social media to reveal Greg was "in the process of starting a chicken wing business, West Wings."
"He created the flavors to his perfection and named them after west coast rappers: Snoop Dog, Kendrick Lamar, Roddy Ricch, The Game, etc.," she said.
She added: "I can say that my son was my favorite chef. He was on to something great and that was his passion."
Boyce's acting career was short-lived -- after appearing in Twilight, he went on to star in a short film titled Apocalypse. He never worked as an actor again.
