Mom leaves quadriplegic son with cerebral palsy in the woods

"For more than four days, police say, a 21-year-old quadriplegic with cerebral palsy was left lying in the woods of Philadelphia's Cobbs Creek Park with only a blanket and a Bible."

"This kid's obviously a fighter,'' [Lt. John] Walker said. "To see that kid laying there, it's heartbreaking to see that another human, especially a mother, could treat someone like that.''

"A lot of things could have happened out there,'' he said. "Obviously, he's in the middle of a wooded area. You have wild animals there. This kid could not defend himself. He does not function at all.''

The son's school became concerned about him and called an aunt. When the mother was contacted in Maryland, police said, she lied about his whereabouts.

"She indicated to both family members and police officers that the child was with her down in Maryland,'' Walker said.

What do you think the bible's roll was in this... callous act?
Maybe, in her mind, the bible was protection? What was she thinking?
Obviously, we are not going to know for certain what she was thinking, but I want to hear some rampant speculation.
