An investigation paid for by Diane Schuler's family turned up "no evidence" to contradict Westchester authorities' findings that the West Babylon mother was drunk and high when she drove a minivan full of children the wrong way on the Taconic State Parkway, a private investigator said Wednesday.
The investigator, Thomas Ruskin of CMP Protective and Investigative, had arranged last spring for independent toxicology tests to confirm or refute a medical examiner's report showing Schuler's blood alcohol concentration was more than twice the legal limit at 0.19 and her levels of marijuana were high.
Ruskin wouldn't say exactly what the new tests showed. But he said: "We have found no evidence of anyone making a mistake."
On July 26 last year, Schuler drove her brother's minivan south into northbound Taconic traffic on her way back from a camping trip, state police say.
Her minivan struck a sport utility vehicle head-on, killing her, her daughter, Erin, 2, and her nieces from Floral Park, Emma Hance, 8, Alyson Hance, 7, and Kate Hance, 5.
