Ramon "B.I." Gomez, who police said pimped out a Griswold teenager in a Groton motel room and sold the heroin that caused her to fatally overdose in May, pleaded guilty to sex trafficking of a minor and heroin distribution charges.

Gomez, 40, a native of New London, entered his plea Thursday in New Haven federal court. He faces a mandatory minimum term of imprisonment of 10 years and a maximum term of imprisonment of life for the sex trafficking charge and a maximum term of imprisonment of 20 years for the heroin charge.

On May 29, Police responded to a 911 call and found 17-year-old Olivia Roark unresponsive on the floor of Room 106 at Flagship Inn & Suites on the Gold Star Highway. Police gave her two doses of the overdose-reversing drug naloxone and transported her to Lawrence + Memorial Hospital, where she was declared dead.

According to court statements and documents from the investigation, Gomez, who knew Roark was under the age of 18, arranged for her to engage in prostitution and sold heroin to a third individual, who then gave it to Roark.

Two other women, Adele Bouthillier and Melissa Crickmore, also were in the motel room.

Bouthillier told investigators that she bought a gram of heroin from Gomez on the morning of May 28 and used it with the teenager. She awoke at 10 p.m. to find Roark unresponsive, and didn't call 911 until 2:36 a.m. May 29, according to a police affidavit.

Groton Town Police and the Regional Community Enhancement Task Force arrested Gomez, determining through witness statements and phone records that he brought Roark to the motel room.

Gomez is scheduled to be sentenced in Hartford on Feb. 10, 2017.

He has been arrested 26 times in Connecticut and, at the time of his arrest in May, was on probation for a 2013 conviction for sale of narcotics.

He and Bouthillier also face federal charges related to Roark's death.
