She always brought a smile into every room she walked into and her laugh was contagious,” said a former classmate of Kylee Monteiro.

The suspect in the murder of 18-year-old Kylee Monteiro faced a judge Wednesday morning where prosecutors recounted Gregory Groom's confession in the incident to Rehoboth police.

The ex-boyfriend of a missing 18-year-old who was 11 weeks pregnant has been arrested after her remains were discovered, officials said.

The day before prosecutors say her boyfriend stabbed her three times, 18-year-old Kylee Monteiro sent an ominous warning to her sister: "If I die it was Greg."

The human remains are consistent with those of 18-year-old Kylee Monteiro, who would be approximately 11 weeks pregnant, Bristol County District Attorney Thomas Quinn said Tuesday.

Remains were found in the search for Kylee Monteiro on Tuesday in Rehoboth, Massachusetts, and her boyfriend, Gregory Groom, is facing charges.

The allegations were detailed in police reports and by a prosecutor Wednesday in Taunton District Court, where Gregory R. Groom pleaded not guilty to charges of murder and assault and battery on a pregnant victim in connection with the death of Kylee Monteiro.

Kylee Monteiro's boyfriend has been arrested after human remains consistent with her were discovered on his property.

The family of a missing Massachusetts teenager set up a GoFundMe to spread awareness of her disappearance and help find her.
