The family even hired a private investigator to try to prove there was a medical reason behind the crash.
Thomas Ruskin, the private eye, says he's got video surveillance to confirm Schuler stopped at an upstate convenience store and a statement from a store clerk that says she asked for over-the-counter pain medicine, according to the
Daily News.
Ruskin says video footage, which hasn't been released, showed Schuler inside and outside the store in Liberty, N.Y. and speaking with the clerk behind the counter. He says the clerk described her as sober less than four hours before the wreck.
"He said she asked him for Tylenol or Advil and he didn't have any - so the question becomes what was bothering Diane Schuler?" Ruskin
told the News.
