Molly Bish Case: Convicted Killer Rodney Stanger's Wallet Sheds Light On Dead Girl's Case

New evidence in the case of a 16-year-old girl killed 12 years ago has police focusing on a convicted killer.

Molly Bish was abducted in June, 2000 from Comins Pond in Warren, Mass. No one has ever been charged in her death.

But MyFox Boston reports that police have new evidence, including a wallet believed to belong to Rodney Stanger, who was convicted in 2008 of killing his longtime girlfriend, Chrystal Morrison. Stanger was already a person of interest in the case.

The wallet was recovered by Morrison's sister, Bonnie Kiernan, who went to the Stanger and Morrison's home in Summerfield, Fla., to retrieve some of her sibling's belongings.

The wallet contains Stanger's Massachusetts Firearms Identification Card, which was renewed on April 17, 2000, just two months before Bish's disappearance.

The F.I.D. card has a picture of Stanger that "bears a striking resemblance to the mystery man Molly's mother, Magi Bish, saw at Comins Pond the day before the abduction," MyFox Boston reports.

Kiernan told the News Telegram she's sure the sketch matches the picture.

“He looks just like the sketch,” Kiernan said. “It's him. I have no doubt it's him.”

Molly's sister said she hopes authorities will take a close look at the newly revealed evidence.

“I'm hopeful the state police will follow up with this,” Heather Bish said. “We appreciate the people that come forward because it gives us a reason to push the investigation.”

MyFox Boston reports that Worcester County District Attorney Joseph Early told reporters he might send Massachusetts State Police investigators back to Florida in an attempt to re-interview Stanger.

Just last month, family and friends of Molly held a vigil to mark the 12th anniversary of her death, according to the Republican.

Family members remain hopeful that Molly's killer will be found and prosecuted.

"We have to keep hoping and we have to keep persevering and we have to keep Molly's memory alive," Heather Bish told the Republic.
