HONOLULU, Hawaii – A convicted thief who was put in charge of an elementary school food program faces felony charges for allegedly stealing more than $37,000 from students.

Ada T. Martin, 51, was charged with multiple first-degree felonies last week for allegedly manipulating Aliamanu Elementary School’s meal tracker computer program to swindle a total of $37,156.31 between 2012 and 2014, KHON reports.

Attorney General Doug Chin announced Friday that Martin was indicted by a grand jury in Oahu on one charge of class B felony theft and a second charge of using a computer in the commission of a crime, a class A felony.

The theft charge is punishable by up to a decade in prison and a $25,000 fine, while the latter charge carries a potential 20-year prison sentence and $50,000 fine.

Chin said Martin was a convicted felon when the district hired her 20 years ago, according to the Associated Press.

Her prior conviction, in 1993, was for first-degree theft and she was sentenced to 5 years of probation, 100 hours of community service, and forced to repay $27,382 in restitution, KHON reports.

“This convicted felon was hired by the Department of Education 20 years ago, and for the past eight years was in charge of the lunch program at Aliamanu,” Chin said in a statement cited by the Honolulu Star-Advertiser. “Kids paid for these school lunches. According to the State, she then pocketed that money.”

Chin told KHON a warrant was issued for Martin’s arrest, and bail has been set at $11,000.

Martin is only the latest school official to stand accused of stealing from students.

Former Carr Lane Visual and Performing Arts Middle School principal Cornelius Green was arrested in late August for allegedly stealing from a school account used for field trips, the St. Louis Post-Dispatch reports.

According to the news site:

While principal of Carr Lane, Green oversaw the school store, which sold candy, chips and snacks to students during lunch, according to a teacher who did not want to be identified. Students also paid $1 to dress down on Fridays.

Green collected and counted the money, the teacher said. It was intended to go toward field trips and end-of-year school events.

In May, teachers had no money to plan end-of-year events, the teacher said. When they tried to pay for buses for a field trip that was scheduled months earlier, the school credit card was declined.

The 34-year-old principal was pulled from the school in June and reassigned to an information technology job as “principal on assignment” before he was arrested in connection to the missing funds Aug. 25.

Green was ultimately charged with two counts of theft after an investigation showed Green allegedly swiped a total $2,200 from a locked closet in a school office, KSDK reports.
