PORTLAND, Ore. -

A 23-year-old nanny stands accused of leaving two children inside a hot vehicle.

Kristin Marie Jones pleaded not guilty in Multnomah County Circuit Court in Oregon on a grand jury indictment that charged her with two counts each of first-degree criminal mistreatment, recklessly endangering another, first-degree child neglect and one county of driving while suspended.

According to the police report, a Portland police officer responded to the Sunblaze Tanning salon to check on the welfare of two children.  The officer said he found a Dodge Caravan with two children inside, both of whom were sweating and screaming.  

While the officer was taking a 3-year-old boy out of the car, he said Jones walked out of the tanning salon.  She removed a 2-month-old girl from the vehicle.

The officer stated in his report that the toddler was "soaked in sweat."  According to court documents, "The officer felt the heat radiating from the child through his bulletproof vest."

The documents stated that Jones told police that she was the nanny for the children and "initially claimed that she left the children with their mother in the car."

A Department of Human Services worker later told the officer that the mother was at work all day.

Police said Jones later admitted she had left the children unattended in the minivan and that she lied because she was scared.
