BOSTON -- The names of more than 200 EMTs who allegedly falsified their training records were released Monday.

Twenty-one Boston EMTs who are members of the fire department are on the list.

The city has some 1,400 members of the department and 800 are also EMTs. Boston EMTs are required, on their own, to keep their certification up to date. The city is cooperating with the state investigation.

Team 5 Investigates has learned 30 members of the Haverhill Fire Department are on the list, and that is not the only controversy in the city.

"I'm concerned about the bad image for the city and the bad image for employees. The vast majority are good," Haverhill Mayor James Fiorentini said.

A firefighter who served four months in jail still managed to pull down a paycheck. Firefighter Kevin Thompson served a secret jail sentence from January to May.

"It's outrageous that someone can be in jail and be on the payroll," one resident said.

By using vacation time and swaps with colleagues, the 52-year-old kept getting paid.

"They should have known about it -- that someone was in jail," another resident said.

"I don't know how he could be out of work for four months. What was he saying? I'm appalled," another resident said.

The city tried to interview Thompson, but he has now filed for retirement with benefits for 27 years of service.

During that time, he racked up a record. According to the Massachusetts Registry of Motor Vehicles, Thompson had a drunken driving conviction in 1977, and he lost his license a decade later for failure to pay excise tax.

In 1992, New Hampshire labeled him a habitual offender after he was found guilty of drunken driving with no license.

In 2008, he was arrested for drunken driving, which led to the four-month sentence.

"I've asked the police department to look into how this man was allowed to be in jail for four months, stay on the payroll and, seemingly, no one knew about it," Fiorentini said.

Haverhill is the same city that hired private detectives last year to take a video of four firefighters allegedly doing strenuous activity after calling out sick.
