The former girlfriend of James “Whitey” Bulger has been transferred to a low-security federal prison in Wascea, Minn., after receiving an eight-year sentence last month for helping the gangster evade capture for 16 years. Catherine Greig, 61, was in the custody of the Federal Correctional Institution in Waseca early Wednesday, according to the Federal Bureau of Prisons website. Greig pleaded guilty in March in federal court in Boston to charges that she harbored Bulger. Bulger, 82, allegedly participated in 19 slayings. He is scheduled to go to trial in March.Travis Andersen can be reached at email@example.com. Follow him on Twitter @TAGlobe.
