MASON CITY, Iowa (AP) -

A Mason City mom has been accused of making her kids sleep in a feces-covered room.

Online court records say 25-year-old Alexis Martinez was arrested Monday and is charged with three counts of felony neglect of a dependent person. Cerro Gordo County Jail records say she remained in custody Tuesday. Online court records don't list the name of an attorney who could be contacted to speak for her.

Court documents say Martinez forced her children, ages 2, 4 and 6, in late August to sleep for a week in a room that had feces on the walls and floor.
