Rambo dad fires gun while driving--while infant son is in car (Phoenix, Arizona)

Hadn't seen any abusive father crap out of Maricopa County for a while, so I guess we were overdue. So anybody want to explain how or why UNNAMED DAD had his infant son in his car, while he's driving through an urban neighborhood, opening fire? We're told he was firing at his girlfriend's father, who was in the car behind him. OOOHH. Like that explains everything. The girlfriend's father, meaning, like, the father of the baby's mother? Or some other girlfriend's father?

INVISIBLE MOTHER ALERT: So there is really no mention of the mother at all here, and why this baby wasn't with Mama instead of crusing around with Rambo Daddy. A little custody/visitation thing maybe? Of course, the press isn't going to tell us how this 9-month-old infant came to be in this car. Even though a ricocheted bullet came within 2 feet of hitting the baby.

PHOENIX - A man opens fire while driving through a Phoenix neighborhood and police say he did it while his infant son was inside the car.

Police pursued the man to his home near 51st Avenue and Camelback.

They say he was firing at his girlfriend's father who was in another car behind him.

Police say the man was really putting his on in harm's way.

"What happened was the bullet..because the aim was so far off, the bullet actually struck the side of his own van, reentered the van and narrowly missed his 9-month old son's head by two feet." said Phoenix Police Lt. John White.

Luckily, the boy wasn't hurt. His father is facing several charges, including child abuse.
