A months-long investigation into allegations of voter fraud in the deep-blue city of Lawrence, Massachusetts has resulted in charges brought against two individuals, one of whom was recently elected to the city council as a Democrat.

Local officials have charged City Councilor-elect Fidelina Santiago and a female associate with voter fraud after video captured criminals raiding voters’ mailboxes in search of absentee and mail-in ballots which were illegally filled out and signed with forged signatures. While the Essex County district attorney has not confirmed either woman is in the video, the city’s police chief confirmed that the video will be used as evidence against them.

Both women are charged with 16 counts of voter fraud.

The lawbreaking was only discovered after one man whose name was forged appeared in person to vote on Election Day and was told he had already voted. He followed up on the mishap with local election officials, who launched a full investigation.
