Killing of Molly Bish

There have been no arrests in the case as of June 2021, but Worcester County District Attorney Joseph Early announced a new person of interest on June 3, 2021, a registered sex offender who died in 2016. Francis P. Sumner Sr., a man with a more-than-20-page criminal record, is being considered in the case. Sumner was found dead inside his Spencer home on May 4, 2016. Early did not say exactly how Sumner was connected to the case, but that investigators recently received new information that has led them to investigate him. On July 9, 1982, Sumner was convicted of aggravated rape and kidnapping from an attack the prior October inside an apartment that Sumner was trying to let. He was sentenced to concurrent sentences of 15-to-18 years on the rape charge and 9-to-10 years on the kidnapping charges. The earliest Sumner could have been released from Walpole State Prison was in 1997. It was not immediately clear how long Sumner was incarcerated for that case. Early said that Sumner was incarcerated several times during his life.

After Gerald Battistoni was named as a suspect, Private Detective Dan Malley and the Bish family asked for DNA testing to be done. Massachusetts state police sent the DNA evidence to Texas. Gerald Battistoni died at Lemuel Shattuck Hospital in Jamaica Plain in November 2014.

In November 2011, Gerald Battistoni, a.k.a. Confidential Informant #62 for the Eastern Hampden County Narcotic Task Force, was named as a suspect in Bish's death by private detective Dan Malley of Massachusetts. Battistoni served time in prison for repeatedly raping a teenage girl in the early 1990s. He attempted suicide in prison after newspaper articles identified him as a potential suspect in Bish and Piirainen's deaths. Battistoni, who had a criminal record dating back to 1980, had been in the area where Bish's body was found and resembles a composite sketch of the man Magi saw in the parking lot on the day before Bish disappeared.

In 2009, a new suspect was investigated. Rodney Stanger, a Florida resident convicted of murdering his girlfriend, had lived in Southbridge, Massachusetts – a few miles from the town of Warren – for more than 20 years. Stanger moved to Florida a year after the Bish murder. Following the murder of Crystal Morrison, Stanger's girlfriend of 20 years, Morrison's sister alerted the Massachusetts authorities. Stanger was known to have access to a white car similar to the one seen the day before Bish's disappearance. He was also known to fish in Comins Pond and hunt in the woods where Bish's body was found. In addition, Stanger closely matched the description provided by Magi Bish of the man seen in the white sedan the day before Molly Bish's disappearance. Stanger has not been charged in her case.

In 2009, when Stanger was being investigated for the Bish murder, police also questioned him in connection with the 1993 murder of Holly Piirainen who went missing in Sturbridge. Bish and Piirainen were the same age in 1993, and Bish had written a letter of hope to Piirainen's parents in 1993. Stanger was not charged in this case. In 2012, forensic evidence led authorities to name David Pouliot — who died in 2003 — as a person of interest in the Piirainen case.

In 2005, a Connecticut resident charged with attempted kidnapping in Connecticut was briefly under investigation in connection with the case.

In 2004, Magi and John Bish founded The Molly Bish Center and Foundation in collaboration with Anna Maria College.

An extensive search was immediately launched. It was to become the largest and most expensive search for a missing person ever undertaken in Massachusetts. Her case was profiled on numerous American television shows, including Disappeared, America's Most Wanted, Unsolved Mysteries, and 48 Hours. A hunter had seen a blue bathing suit in the woods on Whiskey Hill in Palmer, in late fall 2002. In May 2003, he mentioned this to Tim McGuigan, who contacted police. An intense search of the area soon located Bish's body. On June 9, 2003, her body was found 5 mi (8.0 km) from her family home. A cause of death was not determined, but investigators presume Bish was murdered and her remains buried.

In the summer of 2000, 16-year-old Molly Bish began working as a lifeguard at Comins Pond in Warren, Massachusetts. On June 26, the day before her disappearance, her mother, Magi, saw a mustached man in a white car parked in the lot of the beach where Bish's lifeguard post was located. Although he seemed suspicious at the time, she thought no further about him until after Bish's disappearance.

Molly Anne Bish (August 2, 1983 – June 27, 2000) was a sixteen-year-old American girl from rural Worcester County, Massachusetts, who disappeared while working as a lifeguard in her hometown of Warren, Massachusetts. Her remains were found three years later in neighboring Hampden County after what became the largest search in the state's history. Police believe Bish was the victim of a homicide and several suspects have been publicly identified, but the case remains officially unresolved as of 2023.
