There was a Jason Costa that killed Joe Botari and Frank Chuicolo in 1986 in Sly Park in the North End.
According to this article, it was a Louis Costa (age 16 at the time!) and Frank DiBenedetto who were convicted. Ironic that the case may be up for appeal this year with DNA evidence potentially clearing them.
Costa, 16 at the time of the slayings, was convicted for his role in the killings, along with two others. The original verdict was overturned in 1992, and Costa was temporarily set free, but was convicted again, along with Frank DiBenedetto, in 1994. They have been in prison ever since.
The pair have been seeking a new trial since 2005, based on DNA analysis of the blood found on DiBenedetto’s sneakers. Prosecutors said the blood proved DiBenedetto was at the murder scene, but DNA shows the blood did not belong to either of the two victims. Costa and DiBenedetto are using this DNA evidence to seek a new trial.
