A woman fired from her Westport babysitting job was charged last week with stealing and cashing 42 checks worth more than $12,000 from the local family who employed her earlier this year.

Shauna Mauri, 22, of Andrassy Avenue in Fairfield, was charged with second-degree larceny, five counts of second-degree forgery and 37 counts of third-degree forgery. She was released after posting a $10,000 bond and is scheduled to be arraigned on the charges July 2 at Superior Court in Norwalk.

According to the warrant affidavit for Mauri's arrest, Westport police began an investigation after a married couple reported May 17 that someone had stolen dozens of checks and they believed it likely was the babysitter they had just fired.

The couple presented police with 42 forged checks worth $12,685, police said. The vast majority of the checks had been signed by Mauri.

The husband told police that he had met Mauri in November 2011 when she was working at a fitness club. Because the two had a good rapport, he hired her to watch their children.

In February, he began to realize that some checks were missing, and he and his wife suspected that Mauri was taking them.

When police interviewed her, Mauri admitted she took the checks and that she has an addiction to pain killers, the affidavit states.

Mauri said she spent all the money on pain killers, but also gave some money to her mother to help her make ends meet, according to the affidavit.
