DOVER, Del. — A former Delaware charter school leader is facing sentencing after pleading guilty to federal program theft.

Prosecutors are asking for 18 months in prison for Sean Moore, former chief operating officer at Family Foundations Academy in New Castle, at Wednesday’s sentencing.

Prosecutors have also asked the judge to ignore a purported expert opinion submitted by a social worker who says Moore’s criminal behavior was driven by a severe sexual addiction and shopping addiction.

Authorities said Moore stole and misappropriated more than $150,000 in funds belonging to the school.

Moore and the school’s founder and chief academic officer, Tennell Brewington, were fired in 2015 after an audit found repeated personal use of school credit cards.

Brewington pleaded guilty to state charges of theft and official misconduct and was sentenced to probation.
