Sherri Jasper, a Girl Scout board member and counselor at Halmstad Elementary School, leads the program for a candlelight vigil at the school in Chippewa Falls, Wis., Sunday evening, November 4, 2018. Hinkle's mother, Sara Jo Schneider, 32, was also killed. But by Saturday evening, the 21-year-old turned himself in to the authorities. Colten Treu of Chippewa Falls was arrested for the crash.
Treu is being held in custody on suspicion of homicide by intoxicated use of a vehicle and was due to face court on Monday.
Police say a pickup truck veered off the road into a ditch and struck them.
They were all wearing bright safety vests and were accompanied by several adults, the relative said. Treu sped away from the scene, but later turned himself in.
They were picking up trash along the highway when they were cut down.
"Our hearts are broken for the girls and families of the Girl Scouts of the Northwestern Great Lakes", CEO Sylvia Acevedo of Girl Scouts of the US said in a statement Sunday. "Girl Scouts everywhere stand with your during this hard time".

"Chippewa Falls is a close knit community", said Superintendent, Heidi Eliopoulos.
"Our thoughts and prayers go out to the families, friends, fellow students, fellow scouts and everyone else impacted by this", the Chippewa Falls Police Department said.
Police say the 21-year-old driver sped off but later surrendered.
