The Ketchikan Police Department announced two drug arrests on Wednesday, netting about an ounce of methamphetamine and about seven grams of heroin.

According to KPD, Nenita B. Estipona, 51, was arrested July 3 after police intercepted a shipment of methamphetamine. She faces charges of third-degree controlled-substance misconduct and tampering with evidence.

Sergeant Andy Berntson said the street value of that much meth is about $15,000.

He said the heroin charges stemmed from an investigation that wrapped up on Monday. Michael Meacock, 25, was charged with second-degree controlled-substance misconduct for alleged possession of seven-point-two grams of heroin.

Berntson said that amount of heroin is worth between $3,500 and $4,000.

He said both cases were the result of lengthy investigations, and it’s not always clear where the initial information came from.

“So many of these cases overlap, so a lot of times you get people’s names and then months down the road, it’ll kind of come together, which is kind of what happened with both of these cases,” he said.

The police announcement says that the department’s drug dog, Booker, participated in the heroin investigation.
