Martha Coakley, now an attorney for a Boston-based law firm, talks about the prosecution's next steps as they try to prove Brian Walshe murdered his wife, Ana.
Prosecutors revealed a list of grisly Google searches in court, some of which they say Brian Walshe conducted more than an hour before he claims to have last seen his wife.
Authorities charge Brian Walshe, the husband of missing Massachusetts woman Ana Walshe, with his wife's murder as the investigation is ongoing to find the victim.
