Summerville police busted a meth lab Thursday night at the Economy Inn hotel on Holiday Drive, authorities said.

Zachary Allen Kerr, 25, of Oakwood Avenue in Charleston, and Holly Earlene Mahon, 39, of Prestwick Court in Summerville, are both charged with manufacturing methamphetamine. Kerr faces an additional charge of simple possession of marijuana, police said.

Police officers were called to the hotel at 200 Holiday Drive shortly after 7 p.m. following a complaint of possible prostitution, an incident report states.

Officers approached Room 403 and saw a large amount of clothing hanging from a balcony rail.

Two men and two women were inside the room, which police said contained a strong odor of marijuana.

Mahon told officers that someone had smoked pot inside the room but that she made that person leave. However, officers noticed a clear plastic bag filled with the drug was lying on the bed, according to the report.

Kerr told officers that the pot belonged to him.

Police officers also found about 20 Pseudoephedrine pills, which Kerr reported he was taking to treat a cold. According to police, Kerr showed no signs of being sick.

A casserole dish was found on the bathroom floor with a burnt cloth draped over the top, the report states. A plastic bag with a metal cutter and two ice packs were also found in the sink.

Officers determined that the items were being used to make meth, police said.

The room was originally rented to Mahon but was later held under Kerr’s name, police said.

Mahon and Kerr are both being held at the Berkeley County jail, police said.
