An upstate New York music teacher has been arrested and charged with stealing instruments from her classroom, pawning them and using the money to feed her heroin addiction.

Danielle Conner-Willowglade, 30, was arrested after a traffic stop when a trooper saw a tuba in the backseat of her car as she drove toward Rochester.

According to New York State Police, Conner-Willowglade admitted to taking up to 50 instruments from the school and selling them in pawn shops for cash in order to buy heroin.

She was charged with one count of grand larceny, one count of possession of stolen property and one count of possession of a controlled substance.

Her 32-year-old boyfriend, Nicholas Bump, is charged with one count of possession of stolen property and one count of possession of a controlled substance. More charges are pending for both suspects.

Police say Bump would accompany Conner-Willowglade and the two would alternate taking instruments to pawn shops.

Conner-Willowglade was the music teacher at the elementary, middle and high schools in Keshequa, N.Y., an hour south of Rochester. The school district has checked its inventory of instruments, while police have checked local pawn shops. So far the police have recovered 12 instruments and one computer.
