Human remains found at boyfriend’s property is likely missing Mass. pregnant teen, officials say

Human remains “consistent with” 18-year-old Kylee Monteiro were discovered during a search of the Rehoboth residence of a man she was in a relationship with Tuesday night, Bristol County District Attorney Thomas Quinn announced.

The man, 22-year-old Gregory Groom, who already faces domestic violence charges in connection with an incident involving Monteiro, will be charged with murder, Quinn said during a press conference.

Monteiro, who was 11 weeks pregnant, was first reported missing on Aug. 7 by Groom. He is charged with aggravated assault and battery on a pregnant person, domestic assault and battery and intimidation of a witness in connection with an incident involving Monteiro that took place the day prior, Quinn’s office said in a statement.

Groom will be arraigned in Taunton District Court on Wednesday.

Monteiro was last seen at Groom’s residence at 107 County St. in Rehoboth. Police conducted extensive searches for the girl and eventually obtained a search warrant for the County Street property.

During the execution of that search warrant, remains “consistent with” those of Monteiro were found, Quinn said. Officials are awaiting confirmation from the Office of the Chief Medical Examiner that the remains are indeed Monteiro’s.

Videos from the scene show an excavator arriving to the County Street area around 8 p.m. Tuesday.

Monteiro’s family told WCVB she and Groom had argued before she disappeared. Her sister, Faith, wrote on Facebook that the family would be holding a vigil for Monteiro on Saturday.

The family also launched a GoFundMe for Monteiro, which now seeks donations to pay for funeral costs.

“This is closure and we are so thankful for everyone’s help in getting here,” Monteiro’s sister, Catherine, wrote. “Obviously, there will be court proceedings but we are taking this one step at a time.”
