CARROLL COUNTY, IN (WXIN/CNN) – An Indiana couple was arrested after police found them unresponsive, suffering from heroin overdoses, with three young children in their car.

A 911 call from a passerby Friday night alerted police to a vehicle parked in the middle of a road near Delphi, IN.

When emergency crews arrived, they determined the two unresponsive adults inside, identified as 31-year-old Adam Smith and his wife 29-year-old Donnis, were suffering from heroin overdoses.

The couple’s three children, ages 4, 6 and 11, were sitting in the backseat, police say.

The emergency crew administered Narcan to the couple then transported them to the hospital, where they were treated. The two were later turned over to law enforcement to be jailed.

The Smiths were both booked into the Carroll County Jail on preliminary charges of felony neglect of a dependent child. They’re being held on $5,000 bond with additional criminal charges pending.

The children were turned over to the Department of Child Services.

Sheriff Tobe Leazenby says he’s seen this cycle of abuse over and over again in his county.

"They will do almost anything to get that fix, whether or not they place another person or children in jeopardy,” Leazenby said.

The sheriff says his department makes at least one dozen drug arrests each month, and the spike in drug cases has led to overcrowding at his jail.

Leazenby is pushing for more drug treatment centers, but he also has some advice for users who want to get clean.

"I'm not in a position where I'm going to tell people how to choose their friends, but rethink that seriously. Who are you hanging out with, and who are you with? Is maybe some of that the root of your issues?” he said.

Based on statements made during the arrest of the couple, investigators searched a local home and arrested 43-year-old Sara Huff on drug charges, including dealing meth and cocaine.

Investigators say more charges could be filed during the ongoing investigation.
