MIAMI (CBSMiami) – The ongoing criminal investigation into an absentee-ballot request case took investigators to the private office of North Miami Mayor Lucie Tondreau Friday morning.

According to CBS4 news partner the Miami Herald, investigators traced an IP address used to file bulk absentee ballot requests to Tondreau. The investigation is in connection to an unknown number of unlawful absentee-ballot requests submitted online this year. Mayor Tondreau only took office in June.
