Prosecutors say a South Huntington father who confessed to raping his daughter will serve 10 years in prison.

Suffolk County District Attorney Ray Tierney says it happened when the 21-year-old victim was sleeping in his home.

According to court documents, the suspect gave her Advil PM before the assault.

The woman later told investigators that her father abused her as a child.

The father's name is not being released to protect the daughter's identity.
