STAMFORD-A Norwalk sex offender pleaded guilty on Tuesday to reduced charges that he severely injured a two-year-old girl and is scheduled to be sentenced to four years in jail when he returns to court in mid-march. Pedro Salinas, 32, was facing up to 63 years in jail when he was arrested by Norwalk police in July 2016 and charged with a number of offenses including first-degree assault, risk of injury to a minor, first and second-degree sexual assault and the intentional torture of a person under 19 years of age.
