IRVINE  (AP) — A California couple was charged Tuesday with felony conspiracy and false imprisonment for allegedly planting drugs in the car of an elementary school parent volunteer they disliked because they felt she didn't properly supervise their son, prosecutors said.

Kent Easter, 38, of Irvine, planted prescription painkillers, marijuana and a marijuana pipe in the woman's car and then called police to say he had seen her hide the drugs in her car, according to the district attorney's office. Easter was in constant contact with his wife, Jill, by cellphone and text message as he did so, prosecutors said.

Investigators interviewed the school volunteer for two hours but turned their attention to the Easters when they realized the woman was in class at the time Kent Easter accused her of hiding drugs in her car, authorities said. She also vigorously denied knowledge of the drugs.

A video surveillance camera captured Kent Easter calling Irvine police from a business center in a hotel near his legal office, prosecutors said.

Kent Easter did not return a phone message seeking comment Tuesday.

The couple will be arraigned July 17.

If convicted on all charges, they would face a maximum of three years in prison.
