A Holyoke man has been sentenced to up to 10 years in prison for a shooting that injured a 5-year-old boy and his father. Brian Marrero was sentenced Monday in Hamden Superior Court after pleading guilty to assault and battery with a dangerous weapon and illegal possession of a firearm and ammunition. Prosecutors said Marrero, 22, opened fire on Reynaldo Diaz on March 6. Diaz put his son behind him when Marrero started shooting, but one bullet passed through the man’s leg and struck the little boy in the leg. The Republican reported that Marrero had a relationship with the child’s mother, who was the former girlfriend of Diaz.
