Mother, 10-year-old daughter killed when car plowed into Girl Scout troop 'needed to be together'
The suspected driver, Colten Treu, fled but later came forward, police said.
Though Judy Schneider is grieving the loss of her daughter and granddaughter who were killed in an alleged hit-and-run in Wisconsin, she said the two "needed to be together."
Her granddaughter, 10-year-old Haylee Hickle, was among the three young Girl Scouts who were struck and killed while picking up trash along a road this weekend, police said. Haylee's mother, Sara Jo Schneider, 32, was with the Girl Scout troop and was also hit and killed, officials said.
"They needed to be together," Judy Schneider, 53, told ABC Minneapolis affiliate KSTP. "We are hit double, but it needed to be that way. I think God knew that."
In a separate interview with The Associated Press, she said "Haylee would've never made it if she lost her mother. And Sara would've never been able to come back from losing Haylee."
Haylee's father died when she was 3, Judy Schneider told the AP, and her daughter, granddaughter and grandson moved in with her several years ago. Judy Schneider said her 6-year-old grandson doesn't understand that they're gone.
The Girl Scout troop was picking up trash along a county highway Saturday morning when a driver veered out of his lane, crossed over the center line and ultimately drove into a ditch, said Lake Hallie police.
The other Girl Scouts killed in the crash were Jayna Kelley, 9, and Autumn Helgeson, 10, officials said.
A 10-year-old girl was also injured.
All members of the group -- seven children and five adults -- "were in the ditch, not on the pavement or gravel shoulder at the time of the crash" and were "wearing green highly visible safety vests," police said.
The suspected driver, 21-year-old Colten Treu of Chippewa Falls, fled but later turned himself in several hours later, police said.
Treu and his passenger, who also turned himself in, allegedly told police that right before the crash they "had been intentionally inhaling chemical vapors," also known as "huffing."
Treu was huffing an air duster, according to prosecutors, and when the passenger noticed Treu veering, he corrected the steering wheel. The two then got into an argument, after which Treu drove off the road, according to prosecutors.
Eleven charges were filed Tuesday against Treu, including four counts of vehicular homicide, the AP said.
