Molly Bish Murder Investigation: Police Outsource DNA Testing Of Evidence

Investigators trying to crack the abduction and killing of a 16-year-old lifeguard in Massachusetts have sent pieces of potential evidence to an out-of-state lab for analysis, the Worcester Telegram & Gazette reported.

In 2000, Molly Bish disappeared moments after her mother dropped her off to work at Comins Pond in Warren. Three years later, a bathing suit and bones identified as Bish's were found scattered in a wooded area in Palmer.

A spokesman for the Worcester district attorney handling the case wouldn't specify what items got shipped to a Dallas laboratory for tests, the Associated Press reported.

Bish's sister Heather Bish, however, said she expects results on cigarette butts, duct tape and other items picked up at the pond, Fox News said.

Evidence seized from the Florida home of a convicted killer last year also awaits testing, Heather Bish said.

Rodney Stanger was a person of interest in the Bish case before he was convicted of killing his girlfriend in 2008, according to the Daily Mail. He moved suddenly from Soutbridge, Mass. to Summerfield, Fla., just three months after Bish vanished.

Last year, police searched the home Stanger shared with Chrystal Morrison after his deceased girlfriend's sister claimed to find suspicious materials in the home. Stanger's firearms identification card issued by Massachusetts looks extremely similar to the mystery man Bish's mom described lurking around the pond the day before her daughter disappeared.

A video of a blond girl stripping before getting her neck snapped was reportedly among the items taken from Stanger's home.

A backlog at the Massachusetts state police's crime lab compelled authorities to send the items from the Bish files out of state, CBS Boston reported.
