An autopsy will determine if the death of a disabled Texas boy whose decomposing body was found inside a cardboard box was a mere tragedy - or a major crime.

The boy's father was arrested and charged with serious bodily injury to a child after Jonathan Singer's remains were discovered inside the family SUV this past weekend, authorities said.

But the lawyer for Jeffrey Singer, 45, insists the dad had nothing to do with Jonathan's death.

"His position has been from the outset that he did nothing to harm or injure or cause his son's death," said attorney Jim Lindeman. "Something terrible happened to his son and it was a tragic circumstance."At approximately 5 p.m., Bishop began the 45-minute task of unwrapping the Radio Shack ET-290 Lighted Dial Trim-Fone, entombed deep within eight protective layers of packaging. Upon opening the outer cardboard box, he encountered a four-sided cardboard phone-mount which slid out after a pair of styrofoam product-stabilizing blocks were removed. After dismantling the inner cardboard mount, he discovered a freestanding polystyrene shell molded into the shape of the phone's handset and base, with two compartments for the phone's cord and optional wall-mounting screws, both of which were enclosed in factory-sealed miniature plastic baggies. Bishop then removed the polystyrene casing and cut through the underlying layer of protective bubble wrap, giving him access to the phone itself, which was housed in a multi-twist-tie-sealed plastic bag.

"I like this new phone okay, I guess," said Bishop, trying out the white, two-piece unit featuring a backlit multifunction LCD display, dual keypads and an extra-long 10-foot cord. "It's kind of too bad about the other one, though–it was fine except for that one button."

After setting up his new phone, Bishop tossed its box and inner packaging into a garbage bag, and also discarded the Radio Shack bag in which it was brought home. He did briefly keep the sheet of protective bubble wrap, spending several minutes meticulously popping the small air pockets between his thumb and forefinger before throwing it away.

While disposing of the packaging, Bishop said he was careful to set aside the various pieces of literature which accompanied the phone, including a 48-page instruction manual, a booklet explaining the terms of the phone's 60-day limited warranty, the warranty certificate itself, a consumer-opinion reply card, a form for product registration, a catalog of other fine Radio Shack products and a Sprint promotional insert offering Sprint phone cards at a 15 percent discount.
