At least seven human remains found across Connecticut, Rhode Island and Massachusetts between March and April warrant “review and investigation,” according to Pennsylvania-based criminal defense attorney and former Lawrence County District Attorney Matthew Mangino.

Over the last two months, human remains have been located in New Haven, Norwalk, Groton and Killingly, Connecticut; Foster, Rhode Island; and Framingham and Plymouth, Massachusetts. 

It is unclear at this point if the deaths of these seven victims are related in any way, and Connecticut State Police told Fox News Digital on Tuesday that “there is no information at this time suggesting any connection to similar remains discoveries, and there is also no known threat to the public at this time,” regarding the deaths in Connecticut. 

Internet sleuths who are part of a private Facebook page with tens of thousands of members, however, have prompted speculation about a lone-wolf perpetrator. 

“Whether it’s coincidental or not, I think it merits review and investigation, at least,” Mangino told Fox News Digital. “Collaboration between the different jurisdictions to determine whether or not there is some threat out there to individuals — that may be going on as we speak. We don’t know that, but I think it does merit that kind of scrutiny.”

Higgins similarly said that social media “is considered in law enforcement as a two-edged sword.”

“In some respect … it could point law enforcement to other similarities or in a direction they wouldn’t normally have gone. Somebody, just one person as part of this group, might raise an issue that will be that one thread that connects us,” Higgins said. “The other side, of course, is it’s fueling all this attention on this, and it may negatively impact the law enforcement officers … because now you’ve almost tainted a witness pool. People have this slant already that this is a serial killer, and these people were all killed by homicide. So it can interfere.”

The New England Serial Killer Facebook group, which has 57,000 members, garnered more than 10,000 new members last week and over the weekend, as MassLive.com first reported.

Searches for “New England serial killer” on Google spiked around April 7, according to data from the search engine.
