NASHUA – A tip from an out-of-state attorney, who told Nashua police he frequently travels to the Dominican Republic to work with a women’s ministry, has led to the arrest of a Nashua man for allegedly raping a 13-year-old girl nearly four years ago.

Omar Lopez Rosario, 40, of 525 Amherst St., was jailed Tuesday on $10,000 cash-only bail after his arraignment in Nashua district court on two counts of aggravated felonious sexual assault.

Although the charges are felonies, the arraignment and bail hearing took place in district court, rather than Hillsborough County Superior Court-South, because the alleged crimes took place before the Superior Court’s felonies-first arraignment format began last year.

Judge James Leary, who presided at Tuesday’s hearing, scheduled Rosario for a probable cause hearing on April 4 in the Nashua court.

The charges, which are classified as special felonies, accuse Rosario of sexually assaulting the girl at his Nashua apartment between Jan. 1 and May 5, 2015.

Police said when detectives went to Rosario’s apartment several days before his arrest, he agreed to meet them at

police headquarters for an interview. A Spanish-speaking officer was present, police said, as Rosario speaks no English.

Rosario, according to the police affidavit, told detectives he “never violated” the girl. But some of his subsequent statements and answers bordered on the bizarre, such as an exchange in which he told police it was the first time he’d heard the allegations the girl was sexually assaulted.

When police asked him “how this made him feel,” Rosario simply “stated he felt ‘fine,’ and showed no emotion or concern,” police wrote.

Asked if he is guilty of the allegations he assaulted the girl, police said Rosario replied, ‘my god will tell me.’

Later, Rosario allegedly told detectives “he wished to have a ‘deep analysis’ completed” on the girl, suggesting she “might be an imposter” of some kind, the affidavit states.

When told by police the girl “was accusing him of sexually assaulting her,” Rosario stated that “the allegations filled him with faith … and were good for his life,” according to the affidavit.

The series of events that ultimately led to Rosario’s arrest began taking shape in 2017, when the alleged victim’s mother, who lives in the Dominican Republic and is acquainted with the attorney who works at the women’s ministry, told him her daughter had been molested in the U.S., specifically Nashua, two years earlier.

The mother, who volunteers at the ministry, said she believed the attorney could assist her in reporting the alleged sexual assaults “to the proper authorities,” police said.

The attorney later forwarded paperwork to Nashua, which police reviewed, then set up an interview via Skype with the alleged victim and her mother, police said.

Based on the interview and additional information the attorney provided, police said detectives applied for, and were granted, a warrant for Rosario’s arrest.
