Immigration officers arrested a Brazilian national in Massachusetts on October 30 right after he finished serving his state prison sentence for raping a child and related crimes on Martha's Vineyard. Jair Fernandes de Oliveira Junior had been convicted months earlier of offenses that took place in Oak Bluffs in the fall of 2024.
According to New Bedford Guide, U.S. Immigration and Customs Enforcement officers took de Oliveira Junior into custody after he had completed his state sentence. The outlet reported the arrest came in Massachusetts following his release from state custody.
De Oliveira Junior pleaded guilty to charges at a Dukes County Superior Court hearing in Edgartown in April, according to the Martha's Vineyard Times. He was convicted on four of seven indictments brought against him, the paper reported, including rape of a child, kidnapping, indecent assault and battery on a child under 14, and intimidation of a witness. The underlying offenses took place in Oak Bluffs on Martha's Vineyard between October and November 2024.
A Nine-Month Sentence After Credit for Time Served
A judge sentenced de Oliveira Junior to two years and one day at Souza-Baranowski Correctional Center in Lancaster, the Martha's Vineyard Times reported. He received credit for roughly 454 days already served, which the paper noted meant he would likely spend only around nine months more behind bars before his release.
Months earlier, in December 2025, a judge had set cash bail at $20,000 for each defendant in the case, the same outlet reported, citing flight risk and an existing ICE detainer tied to de Oliveira Junior's immigration status. The article noted that the judge who denied the defendants' request for release on personal recognizance also pointed to detainers that ICE had placed on both defendants in the case.
Co-Defendant Also Taken Into Federal Custody
De Oliveira Junior was not the only person charged in the case. Ana Beatriz Dasilva Sousa, identified as his co-defendant, pleaded guilty to a related witness intimidation charge in April, according to the same report. Her other charges, including aggravated rape of a child, were dismissed as part of that plea, the paper stated. Sousa was released directly into ICE custody as she left the courthouse following the April hearing, and she was taken into ICE custody that same month.
De Oliveira Junior was a Brazilian national convicted of raping a child, two counts of indecent assault and battery on a child under 14, and kidnapping. ICE Boston said, in comments tied to the arrest, that another dangerous criminal alien would be held accountable for his crimes.
Legal Framework Around Detainers
Federal detainer procedures under 8 CFR 287.7 describe a justice agency maintaining custody of a person for up to 48 hours, excluding weekends and holidays, to allow federal immigration authorities to take over. Separately, a fact sheet from the Massachusetts Legislature describes legislation that bars state and local law enforcement from detaining someone based solely on a civil immigration detainer, with an exception described as necessary to enforce criminal law.
