Mark Mccreery, 42, of Greenville

MILFORD — Police said Monday that a two-month investigation into the August overdose death of a 30-year-old Milford woman has culminated in the arrest of a Greenville man.

Mark Mccreery, 42, of 80 Main St., Apt. 3, is charged with one count of sale of a controlled drug — death resulting, a special felony that accuses him of selling the drugs on which the Milford woman overdosed and died on Aug. 21.

Mccreery was booked on the charge and chose to waive arraignment, which was scheduled for Monday in Hillsborough County Superior Court South in Nashua.

He is jailed on preventive detention pending his next court date, which is a dispositional conference on Jan. 5 in Superior Court.

Police said their investigation, in which they partnered with representatives of the Hillsborough County Sheriff’s Department, eventually led to Mccreery as the suspect who, police said, allegedly “provided a quantity of fentanyl to the now-deceased female.”

According to court documents filed in the case, Mccreery allegedly drove to the woman’s Milford residence the evening of Aug. 21 and sold her 1.2 grams of fentanyl. The two texted back and forth, with the woman asking Mccreery, “do you have a g,” meaning a gram of fentanyl, according to police reports.

He responded that he did, and told her “it’s way better than before” in text shorthand. Mccreery, the reports state, told the woman “this stuff is like really strong, you gotta be careful for real … .”

The final correspondence between the two was about 8 p.m. Aug. 21 when Mccreery wrote “here,” indicating he had arrived at the woman’s residence.

Just hours later, in the early morning hours of Aug. 22, someone — the reports don’t identify the person — called 911 to report the woman was unresponsive and not breathing and CPR was about to be started.

Life-saving attempts were unsuccessful, the reports state, and the woman was pronounced deceased.

Police had already identified Mccreery as the likely suspect, the reports state. It was when the results of the toxicology tests performed during the autopsy of the woman’s body determined “the immediate cause of death in this case was acute fentanyl toxicity,” according to the reports.

Police subsequently located Mccreery and served the warrant for his arrest.

Police ask that anyone who may have additional information on the case contact Det. Sgt. Daniel Campbell at 603-249-0630.
