Actor Gregory Tyree Boyce has been found dead at the age of 30, along with his girlfriend Natalie Adepoju.
According to multiple media outlets, the Las Vegas Medical Examiners office confirmed the pair were pronounced dead on May 13, although the cause of death is not yet known.
TMZ reports that law enforcement sources said an "unknown white powdery substance" was found at the couple's apartment.
Boyce was best known for his role as Tyler Crowley in the first Twilight film in 2008. His mother, Lisa Wayne, appeared to confirm the news in a Facebook post on Sunday.
"My baby boy, Greg Boyce was the best chef... oh man. He was in the process of starting a wing business, West Wings," she wrote. Wayne added that Boyce's girlfriend had been working with him on his new culinary venture.
"I'm sick without you. I'm torn, I'm lost. I'm in pain," Wayne continued.
"I'd text you or call you when I was broken or worried about something, and you'd tell me, 'Ma, I got you, we'll get thru this together'. Boy. Why did you leave me?"
One of Boyce's own social media posts, written in December as he celebrated his 30th birthday, is eerily foreboding on reflection.
"At one point I didn't think I would make it to see 30 years old," he wrote on Instagram.
"Over the years like everyone else I have made mistakes along the way, but today is one of those days I only reflect on the great ones. What a time to be alive."
E! News reports that Boyce and Adepoju were found by the actor's cousin, who went to check on him when he noticed his car had not moved from outside his house.
