ATLANTIC CITY, N.J. (AP) — A Philadelphia man wanted in the deadly stabbing of his girlfriend at an Atlantic City casino last week has turned himself in. Fifty-nine-year-old Frankie Lane faces murder and weapons charges stemming from the death of Sharon Whaley. The 57-year-old Philadelphia woman’s body was found Friday night inside a room at the Hard Rock Hotel & Casino, according to the Atlantic County Prosecutor’s Office. They say Whaley had suffered multiple stab wounds, but a cause of death has not been determined. Lane was being sought before he turned himself in without incident at the prosecutor’s office on Monday night. It’s not known if he’s retained an attorney. A motive for the attack remains under investigation.
