In a first for Ulster County, an alleged drug dealer has been charged with criminally negligent homicide following an overdose death; in this case, it was heroin laced with fentanyl that killed a woman in May of 2018.

On Monday, Monique S. Dibble, 33, of Marlboro, was taken into custody following a lengthy investigation by the Ulster Regional Gang Enforcement Narcotics Team (URGENT), together with New York State Police, the Ulster County Sheriff’s Office, Town of Marlborough Police and the Ulster County District Attorney. In addition to criminally negligent homicide, Dibble was charged with several counts of sale and possession of a controlled substance.

According to police, the investigation began shortly after the death of Celina Maldonado, 25, of Plattekill in May of 2018 from a heroin overdose. URGENT says it developed information suggesting the heroin contained fentanyl, a powerful painkiller sometimes added to increase potency, and that the source was Dibble. An investigation was begun and over the next several months, attempts were made to infiltrate her narcotics sales network. Beginning in early 2019, URGENT, with assistance from the New York State Police, began periodically purchasing heroin and cocaine from Dibble, with the final purchase conducted recently.

According to police, fentanyl was found in three of the seven purchases. At this point, police say further evidence was found directly linking Dibble to the sale of the heroin Maldonado overdosed and died from.

The investigation is continuing and additional charges may be filed.

    Wake up, the drug war a very lost cause, waste of taxpayer money, waste of time. Let the druggies go drug out, just keep their homeless filth off public streets. Let them go dope out somewhere and od if they are such losers.

    Enough tax dollars, time, and wasted labor has been wasted on druggies who will never quit.

    Legalize all drugs and let the druggies go dope out at the public garbage dump. Good place to build a shelter for them they can sort trash and do their dope. Who cares? not me, just dont tax me for their problems.
