Michael Tylo, Jr. drowned and was pronounced dead at 11:55 p.m. on Thursday in Henderson, Nevada.
"It has already been determined that this was an accident," Clark County Coroner Michael Murphy said. "Looking at the report, it appears that he fell in the pool after having some sort of medical event. It says on the report that he had a seizure disorder.
"We are doing a toxicology report, but that is standard with all bodies that come to us. That information won't be available for several weeks. With this already having a cause of death, like a medical condition, it appears pretty evident that this is reason for him falling in the pool."
A representative for The Bold and the Beautiful told People magazine that "Hunter is not commenting at this time. But I can confirm that her son Michael, who is 19, died yesterday in Henderson, Nevada."
We wish her family the best.
