MILFORD – Milford and Brookline police as well as the U.S. Postal service are still looking for suspects who mailed hate letters threatening to burn down people’s homes because their yards had signs supporting President Trump.

The typed letters stated, “Dear neighbor, you have been identified by our group as being a Trump supporter. Your address has been added into our database as a target when we attack should Trump not concede the election. We recommend that you check your home insurance policy and make sure that it is current and that it has adequate coverage for fire damage. You have been given fair warning. Always remember that it was you who started this Civil War. Be prepared to face severe consequences of your pre-emptive actions against democracy.”

Capt. Craig Frye of the Milford Police Department said his department had not received any additional new information this week.

“Three people in town received letters about how they’re Trump supporters,” he said. “We turned it over to the U.S. postal inspectors and the FBI is involved.”

Brookline Police chief Bill Quigley has said that he was “shocked” that anyone would send out such a letter.

Just days away from Election Day, Trump trails his challenger, former Vice President Joe Biden, according to the latest public opinion polls.

Trump has repeatedly declined to say that he’ll accept the result of the election because of what he alleges is rampant voter fraud.

Frye said that no other letters have been received to his knowledge.

“I don’t know if the postmaster has received any letters,” he said. “Sometimes if people receive mail that they don’t like, they’ll just go down to the post office. And they could be grabbing other letters but I’m not really sure.”

One woman who received one of the letters said the FBI has urged her to install surveillance equipment and cameras. Police are patrolling the neighborhood and residents are on alert.

“It makes me very nervous,” a member of the neighborhood said.
