In October 2005, a Somerville police officer living in Melrose raped his 23-month-old niece with a hot object, most likely a curling iron. Keith Winfield, then 31, told police he was alone with the toddler that day and made additional statements that would ultimately be used to convict him. But in the aftermath of the crime, a Middlesex County grand jury overseen by Martha Coakley, then the district attorney, investigated without taking action. It was only after the toddlers mother filed applications for criminal complaints that Coakley won grand jury indictments charging rape and assault and battery. Even then, nearly 10 months after the crime, Coakleys office recommended that Winfield be released on personal recognizance, with no cash bail. He remained free until December 2007, when Coakleys successor as district attorney won a conviction and two life terms. Some saw Coakley as lax on ’05 rape case - The Boston Globe Yep, she look like the perfect librul to take a seat in the US Senate..
