My thoughts exactly!
No, they were traveling. There is proof that they did not leave the baby unsupervised in a hot car.
They were only 30 minutes away from their destination when they stopped - read the article, read the link in the article - and found the baby unresponsive.
Actually they left the baby to die in a hot car - WHILE THEY WERE ALL IN IT DRIVING THROUGH OKLAHOMA.
