HOUSTON -

A woman was found naked and eating ice cream inside a drug store after leaving three children alone in a car after a wreck, investigators said.

Stephanie Dillard, 34, has been charged with endangering a child.

Houston police said Dillard's children, ages 5, 12 and 16, were in the car with her when her vehicle collided with a METRO bus near South Post Oak and Orem on Friday.

All of the children were shaken up and suffered minor injuries. The 5-year-old had a large gash over one eye, officials said.

Detectives said that after the wreck, Dillard got out of the car and walked away, leaving her children alone at the scene.

Dillard then went to a nearby CVS store and began taking off her clothes as she ate ice cream, police said.

Investigators said Dillard put up a fight when officers tried to arrest her.

The children have been turned over to a grandmother.

Police said they have not yet figured out what caused Dillard's strange behavior.

Dillard is being held in the Harris County Jail with bond set at $2,000.

Dillard's past criminal history includes a 2009 robbery charge.
