The new treasurer found collection notices for invoices Zamora documented as paid, according to police.

“Detectives believe Zamora wrote checks to herself but indicated they were written to pay bills for the club’s coaching stipends and uniforms.  The checks were written for $2,000 to $3,000 each over her tenure as the club’s treasurer totaling approximately $16,000,” police said in a news release.
