The guilty plea on behalf of Scott Rego was entered last Friday in Fall River Superior Court. Rego, 30, was sentenced by Judge Renee Dupuis to 8 ½ to 12 ½ years in a state prison. He initially was charged with a single count of murder in the fatal stabbing of his 36-year-old girlfriend Kristina Reis inside their third-floor Linden Street apartment. Police say they found Reis’s body at around 9:30 p.m. on May 22, 2017, on the porch of the triple decker with a trail of blood leading up to the apartment. They said she had been stabbed twice on each side of her neck with one wound consisting of an entry and exit on both sides of her neck.
