MIAMI – (CBSMiami.com) A treasurer at Miami Edison Senior High is behind bars after police say that for the past five months she fraudulently wrote herself checks and then tampered those checks to make it seem as though the payments were made to legitimate school vendors.

Police say Lisa Bradley, 41, wrote herself 14 checks – each one more than $500 a piece totaling $14,332.44 from August, 2010 to January, 2011.

She would then take the checks to her own personal bank account and deposit them there, police said.

Once the checks were returned to the school at 2521 NW 87th St. as part of the bank’s monthly statement, Bradley would allegedly use white-out to remove her name from the check and replace it with a legitimate school vendor.

Police say she confessed to the crime saying she had financial hardship.

On Wednesday afternoon, she appeared before a bond court judge and was ordered held on $15,000 bond.
