The officer said he had previously warned the mayor that the vehicle wasn’t street legal. In February, according to the chief’s memo, an officer saw Tremblay and Howard driving around in the mayor’s off-road vehicle. He wrote that he did so “due to fears of being terminated because of retaliation against me.” After 21 years on the force - not long enough under state law to qualify for his full pension - Alu took early retirement in March.

Lupo told Alu that he constantly watched him, the memo said, and threatened to fire him.
