The Brian Walshe murder trial continued Tuesday with more testimony from police who investigated the disappearance of his wife Ana Walshe from their home in Cohasset, Massachusetts. Massachusetts State Police Trooper Nicholas Guarino took the stand and testified about Walshe's allegedly violent online search history. Guarino, who said he is on medical leave from his job, also testified earlier this year in the high-profile Karen Read murder trial. | WBZ / CBS News Boston
