Police responding to a call about four dead bodies on a Missouri basketball court found two adults and two children alive but suffering from exposure to the heat, CNN affiliate KSDK reported Tuesday.

Officers in Pine Lawn woke the adults, who said they were merely napping. But the two children, ages 3 and 4, were drenched in perspiration and urine and had steam rising from their bodies, KSDK reported.

The children were hospitalized. The woman, who is the children's mother, was arrested and may be charged with parental neglect, the station reported.

Pine Lawn is 10 miles northwest of St. Louis. The temperature in the area reached 102 degrees Tuesday, KSDK reported.
