An 18-year-old pregnant woman was found buried on her ex-boyfriend’s property in Rehoboth, Massachusetts, after he confessed to police that he stabbed her to death. Gregory Groom, 22, now faces murder charges and is being held without bail. Kylee Monteiro, an Attleboro High School graduate, was 11 weeks pregnant when she disappeared on August 7. She was last seen in the area of Country Street in Rehoboth. Police discovered her body nearly two weeks later, after Groom led police to where he had buried her on the 25-acre property.
Before her death, Monteiro sent a text message to her sister warning her about Groom’s violence. “If I die, it was Greg,” She wrote to her sister that Groom had thrown her to the ground and strangled her, adding “my phone is at 4% and if I die, it was Greg.” The message came on her final night alive.
False Missing Person Report Launches Investigation
Kylee Monteiro had been living at a homeless shelter for pregnant women in Pembroke for several weeks before her death. Her older sister, Faith, told investigators that Kylee and Gregory had an “on and off” relationship with ongoing domestic problems.
On August 6, Monteiro left the residential program and took a rideshare to Groom’s property, hoping to stay with him. That night, she texted Faith about the violence she was experiencing. According to prosecutors, the message read, “He threw me on the ground and pulled my hair and strangled me.” The family tried to get in touch with Monteiro to move her somewhere safe, but she replied that she was trying to stay at Groom’s house. Monteiro disappeared on August 7.
The next day, August 8, Groom contacted police, reporting that his girlfriend was missing. According to his account, Monteiro had come to his house seeking a place to stay, they argued, and she left. He maintained he had not seen or heard from her since. The dispute, he insisted, centered on whether she could remain on his property. Beyond that argument, Groom claimed nothing else occurred before her departure.
Police launched an investigation when friends and family couldn’t reach Monteiro. During questioning, Groom told investigators that Monteiro had taken a rideshare to his house on August 6. She wanted to stay with him, but left after their argument about the living arrangement.
Search Leads Police to Groom’s Property
Six days later, on August 14, police searched Groom’s property but found nothing. On Tuesday, August 20, Groom returned for another police interview. Under questioning, Groom changed his story. He now admitted that on August 6, he had physically fought with Monteiro, pushing her until she fell backward and struck her head. As investigators pressed him about Monteiro’s whereabouts, they told him they had obtained a search warrant for his property and would dig if necessary.
Interrogation Breaks Suspect’s Story
Under pressure, Groom began drawing a map showing a shed on his property where he regularly stayed. He told police the argument between him and Monteiro had taken place there. At that point, he broke down and confessed to the killing.
Groom confessed he had stabbed Monteiro twice in the neck and once in the chest. The chest wound broke off the knife blade, which remained lodged in her body. After the murder, Groom spent several hours digging a hole in the woods about 20 yards from where he had attacked her. He pushed her body into the hole and covered it up after sunrise.
Armed with his confession and search warrant, officers went to his property and found the mound of branches and debris in the woods. Underneath, they discovered a body matching Monteiro’s description. The body was sent to the medical examiner for identification and autopsy.
Legal Proceedings Begin
Gregory Groom faces multiple charges beyond murder. Prosecutors also charged him with assault and battery on a pregnant victim, assault and battery on a family or household member, and aggravated intimidation of a witness, juror, police, or court official.
Bristol County District Attorney Thomas Quinn said it is still too early to determine the exact reason for the murder, but the investigation continues. The District Attorney met with Monteiro’s family on Wednesday and told them to be patient despite their trauma.
Groom pleaded not guilty to all charges during his court appearance last week. A probable cause hearing is set for September 10. He remains in jail without bail.
Community Rallies Around Victim’s Family
More than 100 people gathered Saturday night for a vigil honoring Monteiro’s life. The community held the ‘Vigil of Hope for Kylee Monteiro’ at 7 p.m. at Redway Plain and the Veterans Memorial Gazebo on Route 44 in Rehoboth. Friends, family, classmates, and strangers came together to remember the young woman, releasing purple balloons into the night sky as candles lit up the gathering. Members of Monteiro’s family wore shirts reading “Justice for Kylee.” People who did not know Monteiro personally said they felt moved to show support for her family and the community. “It’s sad, she was just 18 years old, she was just starting her life,” one attendee said, hoping the community could help the family get justice.
Monteiro’s murder has shocked the local community in Rehoboth and the surrounding areas. The recent high school graduate was expecting her first child when Groom killed her. As the legal process continues, prosecutors are building their case against Gregory Groom, and they will likely center their arguments on his confession and the physical evidence from the burial site when the case goes to trial.
