FIRST ON FOX – Matthew Nilo returned to a Boston court Thursday as his defense said it would be "inappropriate" to take a DNA swab from the New Jersey-based lawyer, who has been accused of sexually assaulting or raping at least eight women in the Boston area in 2007 and 2008.

Nilo appeared in Suffolk County court with his fiancée on Thursday for a motion hearing. After more than 16 years, authorities in March linked his DNA to evidence found at the various crime scenes in Boston and Charlestown, where Nilo, now 35, is accused of assaulting eight women between 2007 and 2008, when he would have been 19 or 20 years old.

"The Commonwealth still owes us a lot of information. And our position is: we should … have all that information before the courthouse makes a ruling on conducting an invasive vehicle swab of our client," Nilo's attorney, Joseph Cataldo, told Fox News Digital of Thursday's hearing, referring to a DNA sample that the Commonwealth wants to take directly from the suspect's mouth. "We think it's inappropriate now to conduct such a search."

Cataldo argued that the evidence the state is "relying upon is tainted by the illegal search in the first place, which was conducted in New York" with "the warrantless search and seizure of tableware and DNA."

FBI Boston Special Agent In Charge Joe Bonavolonta said in May that Nilo's arrest was "the direct result of the FBI’s use of investigative genetic genealogy," which he described as "a unique method used to generate new leads in unsolved sex assaults, homicides and other violent crimes."

Prosecutors revealed during a hearing in June that investigators matched a DNA profile left on the three rape victims to the profile of at least one of Nilo's relatives that had been uploaded to a public genetic genealogy database online. They apparently matched that DNA to a sample obtained from a drinking glass Nilo used at a corporate event in New York.

In July, a Suffolk County, Massachusetts grand jury indicted Nilo on seven additional charges, including one count of rape, one count of aggravated rape, three counts of assault with intent to rape and two counts of indecent assault and battery.

"The commonwealth is claiming that they have some connection between Mr. Nilo and DNA from 15 years ago, but that evidence was presumably taken from tableware in New York without a warrant and searching it for DNA," Cataldo said, adding that the alleged DNA evidence was "taken without his knowledge or consent or, most importantly, without a warrant."

"We need that information before we start forcing Mr. Nilo to start undergoing bodily searches," the attorney said.

Pinkham, who said she was working as a bar manager in Cambridge at the time of the 2007 attack, alleged that Nilo forced her into a vehicle at gunpoint near Government Center in downtown Boston. 

Cataldo questioned what he described as "the suspicious nature in which the DNA was recovered, but we'll get to that in due course" in comments to reporters at the Suffolk County Superior Court on June 15.
