Massachusetts Man Indicted in Murder of Pregnant Girlfriend Found Buried on Grandparents’ Property
MASSACHUSETTS — A Massachusetts man has been indicted in the murder of his pregnant girlfriend, whose remains were discovered buried on his grandparents’ property, prosecutors announced this week.
Gregory Groom, 22, is accused of killing 18-year-old Kylee Monteiro, who was 11 weeks pregnant at the time of her death. Investigators say Monteiro’s final text messages to her sister painted a chilling picture of the violence she endured before she was killed.
“He threw me on the ground, and pulled my hair and strangled me,” Monteiro wrote. “My phone’s at 4 percent. If I die, it was Greg.”
According to court records, Monteiro’s remains were discovered in a shallow grave on Groom’s grandparents’ property earlier this year. Police say her disappearance had been reported days before the discovery, and a search of the rural Massachusetts home led to the grim find.
Investigators Detail Evidence of Domestic Violence
Prosecutors say that Monteiro’s final communications, along with physical evidence recovered from Groom’s home, were critical in securing the indictment. Authorities allege that Groom had a history of abusive behavior toward Monteiro and that the couple’s relationship had become increasingly volatile in the weeks before her death.
Court documents reveal that Groom initially denied involvement but later made inconsistent statements during questioning. Detectives also recovered digital evidence — including deleted messages and location data — connecting him to the burial site.
Held Without Bail Since August
Groom was arraigned in August and has remained held without bail pending trial. Prosecutors emphasized that the case represents a tragic example of domestic violence escalating to lethal levels.
“Kylee’s final messages speak for themselves,” one investigator said. “She knew she was in danger. We’re committed to seeking justice for her and her unborn child.”
Community and Family Reaction
Monteiro’s family, devastated by the loss, described her as a kind, hopeful young woman who was preparing to start a new chapter in life. Photos shared by relatives show her proudly wearing her high school graduation cap and gown.
Friends have organized memorial fundraisers in her honor, calling attention to the importance of reporting domestic abuse and supporting victims before tragedy strikes.
