Who is Kylee Monteiro? Understanding the tragic case of the Rehoboth teen

Kylee Monteiro, 18, was reported missing on August 7, 2025, in Rehoboth, Massachusetts, just two months after graduating from Attleboro High School and at approximately 11 weeks pregnant. Concern and urgency spiked when a friend revealed Kylee sent a chilling message before she vanished: “I don’t feel safe right now. Something’s not right.”

Described by her family as timid, heavy-set, and unsure when alone, Kylee’s sudden disappearance deeply alarmed those who know and love her.

The Timeline: From Argument to Tragedy

Kylee was last seen leaving her boyfriend Gregory Groom’s home on County Street in Rehoboth. The day before her disappearance, an argument reportedly unfolded between the couple, signaling tension that soon escalated to tragedy.

Following her disappearance, police launched an extensive search of the surrounding area using K9 units, drones, helicopters, ATVs, and divers. Family members also noted her abrupt silence on social media platforms, especially unusual for someone as active as Kylee.

Arrest and Devastating Discovery

On August 19, 2025, authorities arrested Gregory Groom, 22, initially for assault, intimidation, and battery related to the incident on August 6 . During a court-authorized search of his property, investigators discovered what appeared to be human remains consistent with Kylee’s description.

Groom is now facing a pending murder charge in connection with her death. He is being held without bail and is scheduled to be arraigned in Taunton District Court. Confirmation from the state medical examiner is still awaited to officially identify the remains.
