A lead foreclosure fraud investigator for the state said she and a colleague were forced to resign from the Florida attorney general’s office, unexpectedly ending their nearly yearlong pursuit to hold law firms and banks accountable. Former Assistant Attorney General Theresa Edwards and colleague June Clarkson had been investigating the state’s so-called “foreclosure mills,” uncovering evidence of legal malpractice that also implicated banks and loan serv­icers. Despite positive performance evaluations, Edwards said the two were told during a meeting with their supervisor in late May to give up their jobs voluntarily or be let go. Edwards said no reason was given for the move. “It all happened very abruptly,” said Edwards, who had worked in the attorney general’s office for about three years.
