Gov. Maura Healey downplayed the proliferation of crime in state-run shelters housing migrants and local residents after her administration released thousands of pages of records that show many allegations of rape, domestic violence, and possession of guns and illegal drugs.

A day after a Herald story detailed disturbing incidents at shelters meant to house homeless pregnant women and families with children, Healey said more than 50,000 people have moved through the emergency assistance program over the last three years.

The first-term Democrat said the “vast majority of folks” are complying with rules, kids are in school, and “many of them” are working.

“Those who’ve come through immigration most of them have received work authorizations and are also working. And so relative to that number, the instances have been very few. But I take every, every and I want my team to take and I want shelter providers to take every incident seriously,” Healey told reporters inside the State House Wednesday after an unrelated event.

The reports, which the Healey administration released to the Herald through a public records request and appeal, show incidents of child rape, domestic violence, brawls, drunkenness, drugs, and more in the emergency shelter system.

Their publication comes as the governor is dealing with fallout from the arrest of an illegal immigrant from the Dominican Republic who was allegedly in possession of an AR-15 and $1 million worth of fentanyl, a deadly drug that has fueled overdose deaths in the United States.

Leonardo Andujar Sanchez, 28, was in state custody Tuesday as he faced local charges but was charged Wednesday by federal prosecutors for allegedly possessing five kilos of fentanyl and an assault rifle. His lawyer previously promised to fight the accusations.

Sanchez — who federal officials said unlawfully entered the country through an unknown location and on an unknown date — was scheduled to appear in a federal courtroom in Boston just after noon.

House Speaker Ron Mariano, a Quincy Democrat, suggested extra security could prevent similar incidents in the future.

“Obviously, the guy was an outsider who was staying with someone, brought this stuff in, and I don’t know what else you have to do. You have to start screening better at the door and that’s what needs to be done and I’m sure that’s what they’ll end up doing,” he told reporters. “Why does someone come in off the street who could walk into anybody’s place without being checked or being screened get to stay with these migrants?”

Sanchez’s arrest prompted Healey to order shelter providers to conduct an “inspection” of all emergency assistance units.

The governor said Wednesday that she “will do everything that I can to ensure the safety and the well-being of residents in shelters as well as in the community.”

“That’s exactly why I have ordered the inspections. It’s why we took swift action to remove that individual from the Revere hotel, and we’ll continue to operate that way going forward. I will leave no stone unturned in terms of doing all that we can to ensure the safety and well-being of residents in care and custody there,” Healey said.
