The woman who drove her minivan for nearly two miles the wrong way on a suburban parkway before crashing in a fiery wreck that killed eight people had a blood alcohol level more than twice the legal limit and traces of marijuana in her system, officials confirmed Tuesday.

The unreleased toxicology report apparently reveals that 36-year-old Diane Schuler had a blood alcohol content of .19. The legal limit is .08. Westchester District Attorney Janet DiFiore also said that THC, the main substance found in marijuana, was also discovered in Schuler’s system.

“The toxicology report prepared by the Westchester County Medical Examiner reveals that the driver of the vehicle traveling southbound in the northbound lanes of the Taconic Parkway had a BAC of .19 – more than twice the legal limit. In addition, the report indicates that the driver was operating the vehicle while impaired by marijuana,” DiFiore said in a statement.

“My office, along with the New York State Police, will continue to investigate the facts and circumstances that led up to the collision causing the deaths, so that the public and the families of the victims can understand what lead to this horrific crash,” she added.

The complete toxicology report is expected to be released on Wednesday.

The news could explain why witnesses reported seeing Schuler driving aggressively and erratically long before the fatal crash, which state police reported on Monday.

Schuler, her 2-year-old daughter and three young nieces died in the July 26 crash on the Taconic Parkway in Westchester County after she slammed head-on into an SUV, about 35 miles northwest of New York City.

Three men in the SUV also died. The lone survivors were Schuler’s 5-year-old son and the occupants of a third vehicle that was hit by the SUV. They sustained minor injuries.

Schuler and her family had been returning home to Long Island from a weekend camping trip in upstate Sullivan County — a journey she had made numerous times in the past.

Her husband, Daniel Schuler, told investigators that he left for a fishing trip and his wife headed for home at about 9:30 that Sunday. He told police everything seemed fine when they left the campground.

Schuler, an executive with Cablevision, inexplicably wound up going south in the northbound lanes as motorists sought in vain to get her attention; six drivers called 911 before the collision. Police have not said how fast the vehicles were going at the time of the crash.

State police, who have been retracing her route, said Monday that witnesses reported seeing her red Ford mini-van on both state Routes 17 and 87. They said the van was straddling two lanes, tailgating, flashing its headlights and beeping the horn.

Others saw the vehicle veering from one lane to another and one witness said it appeared as if she was attempting to pass him on the shoulder of the highway. Another witness said the van drove across a grass divider at the Ramapo service area on Route 87.

State police said while they can’t be absolutely certain the driver was Schuler, the description of the vehicle and occupants and the time the incidents were reported “lead them to believe they are one in the same.”

Schuler called her brother, Warren Hance — the father of the three older girls who died — at about 1:02 p.m., saying she was feeling ill and may have been disoriented. He told her to stay put and he would come to meet her, but she apparently disregarded those instructions.

Schuler’s cellphone was found on the side of the highway, just south of the Tappan Zee Bridge, on Route 87, where she made that final phone call.

Toxicology results for Schuler were expected to be revealed later this week. A preliminary autopsy ruled out a stroke, aneurysm or heart attack. last week.
