A second man has been charged in the Nov. 14 heroin overdose death of Amy Jo Flood, 38, of Auburn.

Maine Drug Enforcement Agency and Drug Enforcement Administration agents arrested Scott Harmon Sr., 52, of 16 Washington Park Road in connection with Flood's death.

Officers executed a search warrant at Harmon's home and arrested him Wednesday, according to court and jail records.

Officers believe the heroin Flood used was obtained from Mark Colello, who bought it from Harmon, according to Nicholas Gagnon, a special agent with the Maine Drug Enforcement Agency. Colello was Flood's boyfriend at the time.

Colello, 41, of 29 Washington Park Road was charged Nov. 15 with aggravated furnishing of a Schedule W drug. Schedule W drugs include amphetamines, cocaine and its derivatives, and heroin and similar opiates.

Harmon is charged with aggravated furnishing of a Schedule W drug and unlawful furnishing of a Schedule W drug, both felonies. Harmon is being held at the Androscoggin County Jail in Auburn on $25,000 cash bail pending his initial court appearance at 8th District Court in Lewiston.

Gagnon wrote in an affidavit that he responded to a fatal overdose reported at Colello's home.

Colello allowed Gagnon to look at his cellphone where he could see Colello had ordered "five" from a contact named "Scott." Gagnon understood that to mean Colello had ordered five grams or "tickets" of heroin that morning.

Gagnon told Colello he knew he had made the purchase at 11 a.m. and two hours later, Flood was dead.

Colello confirmed Gagnon's understanding of events and said he bought the heroin from a man named "Scott." Colello described "Scott" as someone Gagnon recognized as Scott Harmon Sr., who lived in a mobile home park and who had been known to sell large numbers of oxycodone pills. His son was in prison for trafficking heroin from his father's home, Gagnon wrote. He was able to confirm Harmon as Colello's drug contact through a search of his cellphone.

Through phone records, Gagnon concluded that Colello had been ordering his drugs from Harmon at least as far back as August, Gagnon wrote. He wrote that he suspected Harmon's supplier was a man named "Ed" who also lived in the mobile home park.

In an affidavit written by Detective Eric Bell, after reading Colello his Miranda rights, Colello told him he had left his home that morning where Flood had been staying and went to a Lewiston location to get a dose of methadone.

He met "Scott" in an Auburn parking lot, where he bought the four doses of heroin for $80, then went home, according to Bell.

There, he split his purchase with Flood, giving her two of the doses. He told Bell he and Flood both sniffed their respective doses of heroin. Twenty minutes later, Colello left home again, he told Bell.

Colello went to an apartment where Flood had lived to gather some of her belongings, he told Bell. Flood had been released four days earlier from prison in Windham, where she had been incarcerated since April.

When he returned half an hour later to his Auburn home, he found Flood slumped in a chair, Bell wrote in his affidavit. She appeared to be asleep, Colello told him.

He leaned in to kiss her on the cheek and noticed her skin was cold, her lips blue. She was unresponsive when he tried to rouse her, Bell wrote in his affidavit.

Colello told Bell he called 911, then stretched Flood's body on the floor and administered CPR until medics arrived. A paramedic pronounced Flood dead at the scene.

Police searched Colello's home after he consented. Four "tickets," identified as small pieces of paper folded and sealed with black tape, were found in the living room area, Bell wrote.
