Benjamin Roach was today jailed for seven years for killing his month-old baby Roxie. See SWNS story SWSHAKE. A man has been jailed for killing his four-week-old daughter by shaking her violently the first time he was alone with her. Benjamin Roach, 24, from Plymouth, had denied the manslaughter of Roxie-Jo Hopkins-Roach, who died in September 2010, but was convicted unanimously. One of her injuries was similar to what might be seen as a result of a road crash, Plymouth Crown Court was told. Roach may have shaken the baby before throwing her down hard onto a sofa or bed, and the baby would have been blind if she had survived, the court heard.
