A Milford woman faces charges for allegedly selling heroin and crack cocaine from her home.

Olivia Dunn, 45, was arrested at her home on Henderson Lane on Wednesday. The arrest came after a three-month investigation into reported criminal drug activity at her home.

During a search of the home, drug agents seized approximately 50 grams of cocaine base (valued at $5,000), 30 grams of heroin (valued at $7,500) a 9 mm pistol and other evidence of drug crimes.

Dunn is charged with two counts of trafficking and two counts of aggravated trafficking. Dunn was taken to the Penobscot County Jail and bail has been set at $50,000.

Jail officials say they are not releasing Dunn's mug shot because of the ongoing investigation.

More arrests are probable, according to police.
