A Sioux City woman is accused of taking over 30-thousand dollars ($30,000) from the bank accounts of up to 19 disabled adults. Forty-eight-year-old Lisa Sembach-Preston  is a former employee of Crossroads of Western Iowa, a nonprofit that helps adults with disabilities and mental illnesses. Sioux City Police Detective Bill Nice says the case has been under investigation since May.

She allegedly took the money over a two-year period.

Nice says officials at Crossroads of Western Iowa began to suspect something was wrong earlier this year and contacted police with their concerns in May.

Sembach-Preston was booked into the Woodbury County Jail on 169-thousand dollars ($169,000) bond.
