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 22-year-old boyfriend of a pregnant teenager who went missing admitted to police that he had gotten physical with her during an argument.

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.

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."
