A Hernando county teenager is accused of killing his mother's boyfriend.

Deputies were called out to the home on Hayes Street in Spring Hill Sunday afternoon.

They said it started as an argument that escalated when the 17-year-old grabbed a knife from the kitchen.

David Floyd, 39, was stabbed in the chest and has been transported to the hospital where he later died.

No one else was hurt.

Detectives said the 17-year-old suspect has been charged with first-degree murder.

Bay News 9 is not releasing the suspect's name as it is not yet known if he will be charged as an adult.
