GRAFTON, Mass. - The deaths of Holly Piirainen and Molly Bish will be highlighted Wednesday on "Dark Minds," an Investigation Discovery program dedicated to unsolved homicides believed to be the work of serial killers.
Grafton resident Piirainen was only 10 when she disappeared Aug. 5, 1993, while on vacation with her family in Sturbridge. Her skeletal remains were found in Brimfield in October 1993.
"Dark Minds" features non-fiction crime author M. William Phelps and criminal profiler John Kelly, who examine unsolved deaths with the assistance of a convicted killer, known only as "Raven," who is serving multiple life sentences for murder.
The program featuring the Piiarainen and Bish killings notes a chilling detail -- after Piirainen's disappearance, Bish wrote her parents a letter. Seven years later on June 27, 2000, Bish, 16, disappeared from her lifeguard post at Comins Pond in Warren. Her remains were discovered in 2003. No formal link has ever been established between the two cases.
Last January, the Hampden County District Attorney's office announced testing in the Piirainen case revealed a new lead -- a link to a Springfield man, David Edmund Pouliot, who died in 2003. A $15,000 reward has been offered for information leading to the case's resolution.
