As investigators dig deeper into the law enforcement response to the deadly school shooting, in Uvalde, Texas, a host of disturbing questions remain about what officers on the scene knew as the attack was unfolding.

The suspects in the shootings at a Uvalde, Texas, elementary school and a Buffalo, New York, supermarket were both just 18 when authorities say they bought the weapons used in the attacks.

Odessa, Texas Mayor David Turner praised authorities for ramming into the hijacked mail truck the shooter was driving and putting an end to his killing spree. The daylight attack over the Labor Day holiday weekend came just weeks after another mass shooting killed 22 people in the Texas border city of El Paso. But Abbott, a Republican and avid gun rights supporter, has been noncommittal about tightening Texas gun laws. He did not elaborate, and a spokesman referred questions to the Texas Department of Public Safety, which didn't immediately respond for comment. Ator fired at random as he drove in the area of Odessa and Midland, two cities more than 300 miles (482 kilometers) west of Dallas.
