A 41 year old Waterburt Connecticut man is pleading guilty to three Springfield murders.
Calvin Roberson was held in federal custody while after being charged with the kidnapping and murder of a Chicopee man who was found dead in a burning car in Hartford.
It was during that investigation that additional information was developed to connect Roberson with three other western Mass murders.
Roberson will be arraigned tomorrow in Hampden Superior Court for the 2006 murder of Loan Nguye as well as Yonaides Pichardo in 2016 and David Pichardo in 2017.
Details are expected during Wednesday's arraignment session/
