Two people who were found unconscious and not breathing Tuesday night in Gray were revived with the overdose antidote Narcan, according to the Cumberland County Sheriff’s Office.

Police say a 911 caller reported that she went to her son’s home on Shaker Road and found his 38-year-old girlfriend unconscious and not breathing.

When sheriff’s deputies and Gray Rescue arrived at the scene, they found the caller’s 34-year-old son also unconscious and not breathing. Signs in the home indicated the two had taken an overdose of heroin.

Both patients were transported to Maine Medical Center and are recovering.

The sheriff’s office and the Maine Drug Enforcement Agency are investigating.
