Missouri mom plotted kidnapping of her 6-year-old to scare him: police

A Missouri mother is behind bars today after police allege she plotted to have her six-year-old boy kidnapped in order to scare him because he is apparently "too nice" to people.

What happened on Monday must have been more than scary for the young boy, as the police department's accounting of events is disturbing.

The Lincoln County sheriff's office said the boy was lured into a man's truck on Monday after getting off his school bus.

The driver, Nathan Wynn Firoved, is a co-worker of the boy's aunt, Denise Kroutil. The boy's mother, 25-year-old Elizabeth Hupp, Kroutil and the grandmother, Rose Brewer, had earlier agreed to arrange the kidnapping to teach him a life lesson, police say.

Here's how events unfolded according to the sheriff's office:

Once in the truck, the young boy was told by Firoved that he would never see his mother again and he would be "nailed to the wall of a shed." When he started crying, Firoved showed him a gun and said he would be hurt if he didn't stop crying. He tied up the boy's hands and feet with plastic bags, and threw a jacket over his head so he could not see. The boy could not stop crying.

He was brought to his own house and put in the basement, where his aunt removed his pants and told him he would be sold into sex slavery. She was angry with the boy that he did not resist her actions, according to the police report.

After a few hours, the boy was allowed to go upstairs and his relatives lectured him about the danger posed by strangers.

"Family members told investigators their primary intent was to educate the victim and felt they did nothing wrong," the sheriff's department said in a statement.

The boy reported what happened to him to authorities at his school and they contacted the Division of Family Services. The boy is now in protective custody.

His mother is in jail, charged with felony kidnapping, and abuse and neglect of a child.

Firoved, the aunt and the grandmother are also behind bars and facing kidnapping and other charges.

None of the charges has been proven in court.
