When Starlin Castro returned to Chicago in mid-January from his offseason home in the Dominican Republic to appear at the Cubs Convention, Chicago police interviewed him at Area 3 headquarters regarding a young woman's allegation of sexual assault from an encounter in September. Now, with spring training over in Arizona, Castro and his Cubs teammates have returned to Chicago and are to work out Wednesday at Wrigley Field in preparation for Thursday's season opener against the Nationals. Police continued to investigate the claim Tuesday, speaking with people connected to the case.
