LAS VEGAS -- A toddler who was found dead inside a car Monday had been left in the vehicle for 17 hours, police said.

Officers got the call at around 8:30 a.m. Monday after one of the child's older siblings discovered his unresponsive body in the vehicle, police said.

Once at the home in the 4900 block of East Cleveland Avenue, officers determined that Jason Rimer, 4, was dead in his parent's SUV.

Jason was left in the car after a family outing, detectives said. Family members said that they forgot Jason was in the car.

Officers took four other children into protective custody while they investigated Rimer's death.

According to the Review-Journal, Child Protective Services had visited the home before, but officials did not disclose why.

Once the investigation is complete, police will submit the case to the district attorney's office for review.

As the temperatures rise, Metro police want to remind parents about leaving their children in cars. They said the extreme temperatures can make the inside of cars deadly for children and pets.
