If Phoenix police are right on this one, then just about nothing was appropriate inside the sedan that crashed head-on into a Chevrolet truck Monday morning.
Police say a 5-year-old boy in the sedan died in the crash, as cops believe the boy not only was not restrained by a car seat, but wasn't wearing a seat belt at all. And he possibly was in the front seat of the car, too.
To make matters worse, Phoenix police say, the sedan's driver, a 19-year-old man, did not have a driver's license, and alcohol impairment is suspected in the 8 a.m. crash.
In fact, police say none of the three occupants of the sedan was wearing a seat belt, leaving all three injured or worse.
Five-year-old Angel Alvarez died, and his 21-year-old mother sustained "serious injuries" in the crash.
The 19-year-old driver was in critical condition but was expected to survive, police said Monday afternoon.
His name hasn't been released because of his "incapacitating injury," and charges against him are pending.
Phoenix police say the 19-year-old was driving north on 37th Avenue when he crossed over the center line, into oncoming traffic, specifically the Chevy Silverado.
The Silverado driver was wearing a seat belt, the air bag went off, and the driver wasn't injured.
Again, the identity of the driver hasn't been released yet, but police say he's facing charges of manslaughter and aggravated assault.
