Oklahoma Man Poses as Autistic, Cons Women Into Changing His Diaper Mark Anthony Richardson conned babysitters into changing his diaper.

July 22, 2011  -- An Oklahoma man was sentenced to three years in prison after he posed as an autistic, diaper wearing teen and conned babysitters into caring for him and repeatedly changing his diaper.

Mark Anthony Richardson II, 21, pleaded guilty to felony sexual battery and seven counts of outraging public decency. He grabbed the breast of one of his babysitters. The seven counts of outraging public decency refer to the seven times one babysitter changed his diaper.

He is accused of conning at least two babysitters into caring for him while he used a pacifier, wore a diaper and drank baby formula.

In October of last year, a woman alerted Oklahoma City police after Richardson spent several days at her home and stayed overnight at least five times. The unidentified woman's daughter had posted on Craigslist advertising her babysitting services, according to a police report.

Richardson responded to the advertisement posing as the father of an autistic, 19-year-old son, according to a police report.

He then showed up at the woman's home posing as a helpless teen who needed to be fed and changed. He is a slight man at 4-foot-9 and weighing 120 pounds.

Richardson, who was previously convicted of arson, demanded that the women change his diaper. He later grabbed the 18-year-old babysitter's breast while she was sleeping.

During his sentencing, Richardson apologized. After serving his sentence, he must also serve five years of probation and register as a sex offender.
