It’s been almost 16 years since that terrible summer afternoon in July 2009 whenDiane Schuler, a 36-year-old doting mother of two young children, took a wrong turn on the Taconic State Parkway in Westchester County, N.Y., and killed eight people, including herself, her daughter and three nieces.

What happened that day shattered many families and still haunts those who were caught up in the tragedy.

“I just drove down the parkway today,” says Thomas Ruskin, a former New York City police detective who spent several months working as a private investigator for Daniel Schuler, Diane’s husband, digging into what really caused his wife’s erratic and ultimately deadly driving.

“There’s often flowers there at the crash site," Ruskin tells PEOPLE, “but today I noticed someone put a cross up in the snow where all the cars ended up.”

“How she ended up traveling southbound on the northbound lane of the Taconic is one of those unanswered questions that I’ll take to my grave,” says Ruskin, president ofCMP Protective and Investigative Group. “There’s no explaining it.”

On the surface, the facts behind the worst car crash in Westchester County in 90 years are fairly straightforward.

Diane was driving a minivan with the five kids and Daniel was in his truck, along with luggage and the family dog.

“The kids were yelling out the window, saying they had fun and couldn’t wait to come back,” campground owner Ann Scott told PEOPLE days later.

During Diane’s drive home, she stopped at a McDonald’s where witnesses told investigators that they saw no signs she was in physical distress. She later stopped at a Sunoco gas station where she reportedly asked a clerk for an over-the-counter pain relief medication that the store did not sell.

At 11:37 a.m. Diane’s 8-year-old niece, Emma Hance, called her father, Warren, Diane’s older brother, to let him know they were running late.

Before hanging up, Warren spoke briefly with Diane, later recalling that she sounded normal.

A half hour later, eyewitnesses began calling 911 to report seeing the red minivan driving erratically and aggressively, darting in and out of traffic, and tailgating other cars.

Emma called her dad back at 12:58 p.m. to relay an ominous message that they were lost and Diane was having difficulty seeing.

“There’s something wrong with Aunt Diane,” the girl said.

Diane had downplayed the situation, saying of Emma and the kids, “They’re just being silly. They’re playing.”

Warren pleaded with Diane to wait where she was on the side of the highway and he would come get them. He attempted to call her back multiple times, but the calls went unanswered.

Police believe that it was sometime around 1:30 p.m. when Diane got back on the road and drove up the exit ramp of the Taconic Parkway and then, according to several witnesses, began speeding at over 80 mph into oncoming traffic — reportedly causing more than a dozen drivers to swerve out of her way.

One of those drivers was Corey Lowe, who previously recounted to PEOPLE what it was like watching the vehicle barrel straight toward them.

“For a minute we were like, ‘Is that a car?’ ” Lowe — who noted that the minivan “wasn’t swerving; she stayed in a straight line” — said in 2009.

“It came speeding past us at like 80 mph,” he said. “It was the eeriest thing I ever saw.”

For nearly two miles other drivers were somehow able to veer out of Diane’s path. Her luck finally ran out near Briarcliff Manor, N.Y., as she rounded a blind curve and collided head-on with an oncoming SUV.

In the blink of an eye, eight people were dead: Diane, her 2-year-old daughter, Erin, and her nieces Emma, Alyson, 7, and 5-year-old Kate, along with the passengers in the SUV, Michael Bastardi, 81, his son Guy, 49, and their longtime friend Daniel Longo, 74.

The only survivor was Diane’s 5-year-old son, Bryan, who sustained a serious head injury that resulted in nerve damage to his right eye.

Those who witnessed the collision and sprang into action afterwards described the scene to PEOPLE in 2009 as nothing short of horrific.

“People were running to the car screaming, ‘We need help, there are kids in there!’ " said Peter Dedvukaj, who pulled four children — two of the little girls were dead — out of the twisted, burning minivan.

“There was nothing we could do. The third girl had a pulse, but she died later. I was crying the whole time,” Dedvukaj said. “The kids weren’t moving. They weren’t breathing. They looked like angels.”

The tragedy took an even more bewildering twist nine days later when Westchester County officials released the results of toxicology tests that revealed Diane had alcohol in her bloodstream that was twice the legal limit in New York.

Police, who discovered a broken bottle of Absolut vodka in the wreckage, described her blood alcohol level as the equivalent of consuming 10 shots of alcohol in an hour. They also found evidence that Diane had smoked marijuana shortly before the crash.

The new details proved unfathomable for some of those who felt they knew Diane best — and infuriated those who didn’t.

“This is so out of the realm of possibility, it just blows my mind,” said her best friend, Christine Lipani, one of several loved ones who told PEOPLE at the time that the Diane they remembered was a devoted parent and virtual teetotaler.

Her husband of seven years echoed that sentiment. “She was not an alcoholic,” Daniel said two days after the autopsy findings were released, insisting that his wife may have been suffering from some sort of medical crisis — such as a painful tooth abscess — that led to the reckless driving.

“I never saw her drunk since the day I met her,” he said.

But others clearly had. By that NovemberThe New York Timesreported Diane’s sister-in-law Joan Schuler had told investigators after the crash that Diane “smoked marijuana virtually every single day of her life” and described her as a “hard drinker.”

The wreckalso drew attention to concernsabout whether busy roadways, including the Taconic, were sufficiently marked to prevent wrong-way collisions, though experts agreed that Diane had to have driven right past warning signs.

“She was definitely drunk and high at the time of the accident,” he says now.

Ruskin says he had a falling out with Daniel and his lawyers after learning Daniel planned to move forward with lawsuits, including alleging that the New York highway where his wife crashed was poorly designed. (There havereportedly been settlementsin at least four of the suits stemming from the wreck; the Schuler family has avoided the spotlight in recent years.)

“I just felt that it was a tragedy,” Ruskin says, “and they should let Diane and everyone else rest in peace and not stir it up further with litigation.”

Jackie went on to write a memoir,I’ll See You Again, andher family started a foundationin her girls’ name, focused on confidence, self-esteem and self-worth. Jackie and Warren also had another child, a girl.

“I thought it was such a sad thing that all those people would never get to know them,” she told PEOPLE in 2013. “Now, in a way, they will.”

All these years later, Ruskin continually asks himself the same question that so many others have asked.

“To this day, I have often wondered — was she trying to commit suicide or was she so intoxicated that she didn’t even know what she was doing?” he says. “Would she really want to hurt herself with all those little, innocent children in the car? That’s something I don’t think we’ll ever know.”
