Nilo has been 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, according to Boston police.
"This arrest cumulates the investigation that employed the use of genetic genealogy from recovered evidence. All four cases are DNA connected," Boston Police Commissioner Michael Cox said at a press conference. "These investigations utilized sexual assault evidence collection kits with the assistance of detectives in identifying the suspect as the investigations continued," Cox said.
Efforts were launched in May 2022 to review unsolved sexual assault cases that posed the most threat to public safety, Cox said.
