Michael Harroo, 47, of Trinidad, was convicted yesterday in Suffolk Superior Court on several counts of rape, incest, indecent assault and battery and assault with a dangerous weapon, the Suffolk County DA's office reports.

Suffolk County prosecutors charged Harroo first began raping and beating a female relative, then 14, on Trinidad, then continued raping her when both came to Boston for visits with relatives on Warren Street. Finally, at age 18, she went to Boston police. Harroo was indicted here in March, 2006, then arrested on Trinidad and flown here for trial. He will be sentenced Monday.
