Investigators looking into whether a couple actually fed their dog LSD say necropsy results have come back, and there was no trace of the drug in the dog's system.

Nicholas Modrich and Jamie Hughes, of Snellville, were arrested after neighbors called 911 saying Modrich ran naked down Pinehurst Road in Snellville. Hughes, partially clothed, then chased after him.

Police said the couple was high on LSD.

"When he went outside naked, I went chasing after him and I think that's when the dog got out," Hughes said.

When officers arrived, they said they discovered the couple's dog, Oscar, had been hit by a car and the couple needed medical attention of their own.

According to a police report, the couple admitted to taking the drug. But the report said they told the officer they had also given acid to their dog.

The couple told Channel 2's Kerry Kavanugh they never fed the dog LSD.

"I guess the story got twisted because somebody said we fed him LSD. We never did that. We were just concerned about where our dog was," Hughes said.

Necropsy results have come back, confirming that was indeed the case.

The couple faced minor drug and disorderly conduct charges from the incident.
