BLAIRSTOWN, N.J. -- A girl who was dubbed Princess Doe after her remains were found 40 years ago in a New Jersey cemetery has been identified as a Long Island teenager, authorities announced Friday.

Charges have been filed against the man they believe killed Dawn Olanick, 17, of West Babylon, New York, the Warren County, New Jersey, prosecutor's office announced. The suspect, Arthur Kinlaw, 68, is currently serving 20 years to life in Sullivan County, New York, on two first-degree murder convictions.

Kinlaw tried to lure Olanick into prostitution and killed her after she refused, authorities said, according to Lehigh Valley Live. Her remains were found July 25, 1982, in Cedar Ridge Cemetery in Blairstown, in northwestern New Jersey near the Pennsylvania border. Authorities have said she was beaten beyond recognition.

Residents of the area gave her a burial, and she became known as Princess Doe, a name given to her by investigators who sought to identify her. Her burial site contains a gravestone that reads: “Princess Doe. Missing from home. Dead among strangers. Remembered by all.”

Information about a lawyer who could speak on Kinlaw's behalf about the new charges wasn't immediately available.

Olanick’s identity was finally confirmed April 29, authorities said.

“For 40 years, law enforcement has not given up on Princess Doe,” Warren County Prosecutor James Pfeiffer said Friday during a news conference with New Jersey State Police and other law enforcement and assisting agencies.

Kinlaw confessed to the Princess Doe slaying in written statements dating to 2005, authorities revealed Friday. But the prosecutor said that determining the victim’s identity was crucial to assembling a solid case.
