An ambulance medical emergency call about a man who was blue in appearance led Danville police to file heroin charges against him and a woman.

It’s at least the second time this year police in Danville have filed drug charges after incidents in which ambulance crews were summoned to apparent drug overdoses.

Michael Foust, 29, of 509 Railroad St., was arraigned Monday by Montour County District Judge Marvin Shrawder and released on $10,000 unsecured bail.

Lora Hartman, 23, of the same address, was arraigned earlier and released on $5,000 unsecured bail.

Police charged Foust and Hartman each with heroin possession and possession of drug paraphernalia.

A Danville ambulance was called to the home June 4. Scott Lynn Jr., of the ambulance service, requested help from police after he couldn’t gain entry to the home, heard yelling and screaming inside and believed a fight was going on, according to the charges.

Danville Police Chief Eric Gill and ambulance personnel again knocked on the back door and a man, known as Novotny, let them in.

Police and ambulance personnel found Foust and Hartman in the shower, with Foust visibly ill and blue.

In the living room, police said they found a hypodermic needle, a spoon with residue, three open, small, clear plastic bags with a white powder inside and an unopened plastic bag with white powder inside.

In a January incident, three people were charged after an ambulance was summoned to 209 Center St. In a court hearing, a paramedic testified that Paul a McMann, 54, and her husband Thomas McMann, 58, both would likely died from drug overdoses if rescuers had not been summoned. William I. Goodman II, 51, and the McCanns, were all charged with drug-related counts stemming from the incident.

Police said that when they investigated they found $2,500 worth of heroin in the home.

Goodman is awaiting sentencing on a tampering with evidence charge, while the other charges against him were dropped as part of a plea deal. The cases against the McManns are still pending, with hearings scheduled for later this month.
