Chapel Hill Police have made several arrests in recent weeks involving heroin.

Lieutenant Josh Mecimore says two arrests were made as part of a narcotics investigation that dates back to July of last year.

“There was an arrest on March 4 of an Allison Elizabeth Murrow for trafficking heroin, maintaining a dwelling for the purpose of trafficking heroin, and possession with intent to sell and deliver heroin,” he says.

“And then Nathaniel Corwin [was arrested] for the exact same charges but an additional charge of possession of a firearm by a felon.”

Mecimore says, in this case, 6 grams of heroin were recovered, as well as 4 grams of marijuana, and more than $800 in cash. He could not provide further details because the investigation is ongoing.

He adds, in an unrelated incident, additional arrests were made on drug charges, including possession of heroin.

“The amount seized in that was .9 grams, an additional .8 grams of marijuana, and then two cut straws with heroin residue,” he says, “and a glass pipe typically used for smoking marijuana.”

In this case, 25-year-old John Trevor Colvin was charged with felony possession of heroin, and 22-year-old Neil Joseph Colvin was charged with misdemeanor possession of marijuana.

Mecimore says those arrests were the result of a traffic stop.

“An officer ran a license plate on a vehicle,” he says. “The tag was no longer assigned to a vehicle; it shouldn’t have been on a vehicle. So the officer stopped the driver.”

All four suspects mentioned in these two separate cases made their first court appearances in Orange County Court on Monday.
