The assault rifle-toting madman who killed seven people and wounded more than 20 others in a roving Texas spree was identified Sunday as Seth Ator.

Ator, a 36-year-old resident of Odessa, Texas, was first named as the assailant by CBS News, citing law enforcement sources.

When his gold Toyota pickup truck was pulled over for a minor signaling infraction along a stretch of I-20 near Midland, Texas, on Saturday, Ator blasted approaching state troopers, seriously wounding one, authorities have said.

He then peeled off, firing indiscriminately with his AR-style rifle out of the truck as he floored it toward Odessa, authorities said.

Along the way, he killed a Postal Service worker and hijacked her mail truck, continuing the spree, officials said.

He made his last stand in the parking lot of an Odessa movie theater, where he was killed in a shootout with cops as horrified onlookers prayed for their lives.

Authorities have yet to identify a concrete motive behind the onslaught.
