YONKERS - Authorities are looking into whether a man just arrested for two murders in Indiana may be a person of interest in the disappearance of Lauren Spierer.

Bloomington, Ind. police have assigned a detective to check out the mounting case against serial killer William Clyde Gibson III. Gibson is a convicted sex offender who has reportedly confessed to killing two women. The remains of a third woman were found in his backyard last week.

Today marks 11 months since the Edgemont native disappeared after a night of partying at Indiana University. Police have followed up on thousands of leads and have tested remains on several people found in surrounding areas, but there's been no trace of Spierer.
