Natalee Holloway Update: Bone is Not from Missing Teen

NEW YORK (CBS) Aruba authorities issued a press release Tuesday, saying that a bone found on a beach on the island is not from missing American teen Natalee Holloway.

According to the release from the prosecutor's office, the Netherlands Forensic Institute compared a tooth on the piece of jawbone to Holloway's dental records and the analysis "excludes the possibility that the bone material found in Aruba is that of Natalee Holloway."

The release also says that DNA testing was halted after the comparison of dental records excluded Holloway, but that the DNA extracted from the fragment was of "low quality."

Holloway disappeared during a senior class trip in 2005. She was last seen with Joran van der Sloot, who was arrested twice in connection with her disappearance, but never charged.

Aruba prosecutors have repeatedly said they lack evidence to charge van der Sloot, who is currently in jail in Peru accused of killing 21-year-old Stephany Flores on May 30 - five years to the day after Holloway's disappearance.
