MURRAY, Ky. - A middle school teacher trying to buy pot was arrested after she sent text messages to state trooper instead of a dealer, police said.

Trooper Trevor Pervine was at dinner with his wife and parents celebrating a birthday when his phone started buzzing with messages about a marijuana purchase.

At first, Pervine thought the messages were from friends playing a joke, Kentucky State Police spokesman Barry Meadows said. But a couple of phone calls put that idea to rest, and Pervine responded to set up a meeting, Meadows said.

Authorities say Ann Greenfield, 34, arrived at the meeting point and found Pervine and other law enforcement officers waiting for her.

“She learned her lesson. Program your dealers into your phone,” Meadows said.

Greenfield, a teacher at Murray Middle School, was charged with conspiracy to traffic in controlled substances within 1,000 feet of a school, possession of marijuana and possession of drug paraphernalia, Meadows said.

She was suspended with pay pending results of an investigation, the Murray Independent School District said in a statement posted Friday on the district’s Web site. A message seeking comment left at a listing for an Ann Greenfield in Murray, Ky. was not returned.
