Death at the Ballpark

Shea Stadium - Home of the National League New York Mets

A fan at the ballpark yesterday, presumably on license, fell over the railing of an escalator to his death while leaving the par after the game with his family. Some interesting facts:
* Family (incl. "two young daughters") was with him, saw him fall to his death.
* Not injured by a normal "part of the game."
* Foreseeablity
-Another fan had fallen off of an escalator to his death in 1985.
-There is no mention of renovations to the escalator railings post 1985 -is this relevant?
* Reasonableness of Foreseeability
- Only ONE other similar accident in past 23 years.
- Was there EVER another such accident (besides the 1985 accident)?
- How many millions of fans have safely traversed the same route?
*Further interesting notes:
- Cousin stated victim was "holding the railing" and "walking," [not running,] when he "slipped."
- This is Shea's last year in existence. Any chance the owners consequently chose not to invest in some important renovations?
* Is there a duty?
* S/L? Negligence?
