A New Jersey-based lawyer was identified as a suspected serial rapist of at least eight women in the Boston area between 2007 and 2008. And in May Mathew J. Nilo was arrested 16 years after the crimes. 

Authorities linked Nilo's DNA to DNA found at the various crime scenes in Boston and Charlestown, where eight women were assaulted. Authorities claim Nilo lived in the city at that time.

In May the suspect was initially charged with three counts of aggravated rape, two counts of kidnapping, one count of assault with intent to rape, and one count of indecent assault and battery. He pleaded not guilty to all charges.

At the time, Nilo was required to wear a GPS tracking monitor and was released on $500,000 bail.

On June 27 a Suffolk County, Massachusetts grand jury indicted him on seven additional charges. This includes 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.

On Thursday, July 13, the court ordered Nilo, to pay an additional $50,000 cash bail due to the increased charges.

He cannot contact any of the victims in the case and must stay 1,000 feet from Charter Street in the North End of Boston, which was where several of the alleged assaults occurred. And his passport has been revoked.

If he wants he may return to his home in New Jersey with his GPS ankle monitor, but his passport has been revoked.

Who is Nilo?

After the attacks, Nilo got his bachelor's degree from the University of Wisconsin - Madison. He worked as a paralegal. Then got his law degree at the University of San Francisco School of Law. 

He worked at the Clyde & Co. law firm in San Francisco and Atheria Law in New York City.

And according to his LinkedIn page, he was employed at Cowbell Cyber a New York-based cybersecurity company at the time of his arrest.

According to his social media posts, 35-year-old Nilo recently got engaged.

His fiancée has appeared by his side at every court appearance.

Serial rapist allegedly led a double life

"The double life comes with the territory," forensic psychologist Kris Mohandie told Fox News Digital claiming that a serial rapist could appear to return to a normal life after allegedly committing the various assaults when he was 20 years old.

"This new [DNA] technology has unlocked the door to identifying suspects that otherwise would not have been identified."

"They could be a police officer, they could be a pastor in a church, they could be a teacher, they could be a homeless person. They could be all walks of life," Mohandie said. "But the core of it is that they are living a double life because they're concealing this offending, and they are engaging in it."

The forensic psychologist added that when the urge to re-offend becomes stronger the person living a double life can become dangerous again. If the opportunity to re-offend presents itself, criminals might preplan illegal activity.

"There's a presumption that on the surface of a person who seems live a lifestyle of employment, of advanced education, that somehow that is incompatible with continued offending. And we don't know that to be the case," he said. 

"If, indeed, this is a person that is ultimately found criminally responsible … we don't know that there aren't other victims, which is why they are looking every place that he's ever been or visited to see if there are any other cases that fit similar patterns."

Serial offenders, he said, tend to "keep offending until they get caught," even if they have "cooling periods" in between offenses, either because they think authorities are on their trail or because they might simply be busy with "other relationships that are preoccupying them."

"But when push comes to shove … these urges, they don't go away," Mohandie said.

The suspect pleads not guilty

Mohandie emphasizes that Nilo is innocent until proven guilty in court. He is profiling any criminal suspect when he says that leading a double life is not uncommon.

"Mr. Nilo denies all the allegations, including the latest charges," his attorney, Joseph Cataldo, said. "You can expect both a legal and factual challenge to the government's case."

“I think they’re trying to solve some unresolved cases, and I’m afraid that the government might be piling on, just trying to claim that Mr. Nilo committed these crimes,” Cataldo said. And the district attorney’s office was “piling on.”

Earlier this year, at a corporate event, Nilo’s DNA was taken from a drinking glass he used to make the match. Police did not get a warrant for the DNA. Cataldo questioned the constitutionality of how the DNA evidence was obtained and collected.
