The MTV star was 43 years old at the time of his March 29, 2018 death. He died at Phoenixville Hospital in Pennsylvania.

"While some progress is being made in the battle against substance abuse, we continue to lose too many members of our community to this epidemic," Chester County Coroner Dr. Christina VandePol told RadarOnline.com. "Speaking with families like Mr. Lancaster's, I hear so often about how difficult it is to fight addiction and how we are losing talented and loved people to this disease."

Brian's mom Mary exclusively told RadarOnline.com in April, "At this point, it was heart failure."
