Two Child Haven employees and a former employee could face child neglect charges for leaving a 4-year-old girl inside a van for 40 minutes during a 102-degree day in July, the Metropolitan Police Department said Thursday.

Police last week sent the results of its investigation to the Clark County district attorney's office for possible prosecution, said Lt. Brian Evans of the police abuse and neglect unit.

District Attorney David Roger said he will review the case and decide whether the three workers should be prosecuted. But the district attorney's office generally doesn't prosecute cases in which children are left in vehicles unless authorities can prove the act was intentional.

Evans said police are treating the case like any other involving a child left inside a vehicle. "I don't think they meant to leave the kid in the van," Evans said. "But is it neglect? Because the child was in their care."

One of the workers involved in the incident is no longer with the county, county spokeswoman Gina Olivares said via e-mail.

Olivares said the actions of the other two "were addressed as a confidential personnel matter."

The girl, whose name was not released, was left in the Child Haven van after a mix-up over how many children were inside it when it returned from a movie July 26.

Evans said the child was discovered after a nurse at Child Haven heard the girl crying. Authorities had to pull the girl out of the van through a window because the van remained locked, he said.

After the incident, county Department of Family Services Director Thomas Morton said he would change the way children are counted when they are transported. Rather than taking a numeric count, the department will account for children by name, he said.
