The Maine Drug Enforcement Agency arrested three people in Auburn on heroin and cocaine charges Monday.

Monday afternoon, MDEA agents from the Western District Task Force and Auburn police assisted probation and parole officers in locating Mandy Chouinard, 28, of Auburn, who recently stopped reporting to her probation officer, said a Tuesday news release from the Maine Department of Public Safety.

Agents located Chouinard at 1252 Hotel Road in Auburn, the residence of Steven Webster, 39.

Joshua Stevens, 29, of Auburn and Chouinard’s 5-year-old child were at the home as well.

A search of the residence by drug agents and Auburn police turned up 60 grams of heroin, 6.6 grams of cocaine, electronic scales and an AR-15 assault rifle, the release said.

Drug agents said the street value of the drugs was $12,000, and the heroin, destined to be sold in the Lewiston-Auburn area, was the equivalent of 600 dosages.

The trio was arrested and transported to the Androscoggin County Jail.

Stevens is charged with trafficking in scheduled drugs, possession of scheduled drugs and endangering the welfare of a child. Bail was set at $10,000.

Chouinard is charged with endangering the welfare of a child and possession of scheduled drugs. Bail was set at $2,500.

Webster is charged with possession of scheduled drugs. Bail was set at $2,500.

The three are expected to appear in Androscoggin Unified Court on Wednesday.

The Department of Health and Human Services was contacted to provide care for the child.
