No one saw Danny Keysar die on that beautiful spring day in Chicago 12 years ago. But it was painfully easy to tell what happened.
At 16 months, Danny was a cheery little boy. He never tired of "Twinkle, Twinkle Little Star," preferred chewing on crayons to coloring with them, and loved to play peek-a-boo and bark back at dogs.
After lunch, Danny went to bed in the nap room of his day-care center. Apparently he climbed to his feet after waking - normal toddler behavior but risky to Danny in ways no one imagined.
All investigators could say for sure was that Danny choked to death in the collapsing side rail of a Playskool Travel-Lite portable crib. The flimsy lock in the middle of the hinged rail hadn't held. His own weight, all 25 pounds of it, was enough to strangle him in the V-shaped rail, tightening around his neck like an animal trap.
