MCALLEN - A child is still alive thanks to a 9-1-1 caller after a one-year-old boy was found inside a car on one of the hottest days of the summer.

McAllen police tell CHANNEL 5 NEWS, no child younger than 7-years-old can be left in a vehicle unattended.

Sergeant John Saenz explained what residents should do if they notice a child left inside of a hot car.

“If it’s an emergency situation where the child, let’s say passed out, you can tell the signs of a heat emergency coming on with the child, obviously you have to take the next step. Report it to police and if you have to intervene, intervene," he says.

Shopper and parent Rosie Barron agrees with Saenz.

Barron explains some of the things she does when her children are in the backseat.
