The 41-year-old son of Lou Bellamy, founder of the Penumbra Theatre in St. Paul, died while being held in the Hennepin County jail, a Sheriff's Office spokesman said Monday.
Lucas J. Bellamy of Minneapolis was found unresponsive in his cell Thursday afternoon, spokesman Jeremy Zoss said, and died that night. He had been jailed since July 18.
Family members said his death was likely connected to his chronic drug abuse.
"Medical aid was rendered by staff and paramedics," Zoss said. "They continued emergency medical treatment until he was pronounced dead."
Authorities had yet to comment on what led to Bellamy's death, which remains under investigation, Zoss said.
Family members said Bellamy was arrested in Maple Plain, and court records show he was charged with fleeing police in a suspected stolen vehicle and possession of brass knuckles.
"He was driving a car that didn't have any plates, which drew their attention, and he tried to flee," said his mother, painter Colleen Bellamy. He had a passenger in the car who was released by authorities.
"Lucas was under the influence, and they supposedly took him to HCMC, where he was observed for three hours," his mother said. "He had said something about ingesting some drugs."
