BOSTON (CBS) – After 18 years, there is a possible break in the Holly Piirainen murder case.

Investigators say recently discovered evidence has led to new developments. They plan to reveal exactly what that is Tuesday morning in Springfield.

Someone kidnapped 10-year-old Piirainen outside her grandmother’s Sturbridge home in 1993.

Hunters discovered her remains in a wooded area several months later. There have been no arrests.

Sources tell the I-Team that investigators are going to name a man as a possible suspect in the case.

That man, David Pouliot, died in 2003 at the age of 49. He lived in Springfield.

Police are only saying they have forensic evidence from the crime scene and they’ll make a plea for more help from the public.

Pouliot still has family in Springfield. WBZ reached out to them, but they did not return any phone calls.

The press conference is scheduled for Tuesday morning at 10:00 a.m.
