When you make a bank deposit, you can mark a box indicating cash or a check -- but there is no box for cocaine.
The envelope Kendl Murphy gave the teller at Rockville Bank in South Windsor, Connecticut, on Thursday contained a small bag with white powder, police said.
After seeing the unusual deposit, bank staff asked Murphy to wait for her transaction to be completed and other staff members notified the police.
Cops brought a chemical field test kit and determined that the powder was cocaine and arrested Murphy, 43, of Wethersfield.
She was charged with possession of narcotics and possession of narcotics within 1,500 feet of a school or daycare center.
Murphy was released on a $1,000 bond and is scheduled to appear at Manchester Superior Court on Aug. 26.
