– Clad in bright lime-green safety vests, two small groups of Girl Scouts and their adult companions walked along both sides of County Road P in western Wisconsin’s Chippewa County late Saturday morning, chattering and laughing as they picked up litter. 
  
 The fourth-graders had adopted that rural road and performed the community service along it before, clearing the stretch that runs through farmland and residential areas just northwest of Lake Hallie in the spring and fall. 
  
 Suddenly, a black pickup speeding by veered off the road into the shallow ditch where some of the girls were walking, striking several children and a woman accompanying them. The truck then lurched back onto the road and sped away, according to police and witnesses. 
  
 Left behind was a scene of horror — two girls and the chaperone lay dead by the roadside. Two other Girl Scouts were taken by ambulance and helicopter to a hospital, where one died later Saturday. 
  
 The surviving girl remained hospitalized in Rochester late Saturday in critical condition. 
  
 The driver of the pickup that hit them, 21-year-old Colten Treu of Chippewa Falls, later surrendered himself, according to Sgt. Daniel Sokup of the Lake Hallie Police Department. 
  
 Treu was being held at the Chippewa County jail, where he is expected to be charged with four counts of homicide through the negligent use of a vehicle, Sokup said. 
  
 Authorities say the crash occurred before a hill and there were no blind spots. It’s unclear whether Treu was somehow distracted at the time, he said. 
  
 A relative of one of the girls who escaped injury said all of the children were Scouts who attend Halmstad Elementary School in Chippewa Falls. They were bagging litter in the grassy area between the road and a farm field near the Hwy. 29 overpass about 11:40 a.m. while another small group worked across the road when Treu’s Ford F-150 plowed into them, according to the relative, who didn’t want to be identified. 
  
 Within hours, social media tributes began circulating online to honor Troop 3055. The troop’s regional council, the Girl Scouts of the Northwestern Great Lakes, announced the news on Facebook. The post asked that supporters keep the affected families in their “thoughts and prayers as they grapple with this senseless loss.” 
  
 ‘All hell broke loose’ 
  
 A neighbor who lives down the road from the crash site said he saw a group of about 10 Girl Scouts walking along the roadway wearing their safety vests about 11 a.m. 
  
 Not long after, “All hell broke loose,” he said. 
  
 The man, who declined to give his full name, said he never heard the truck but saw emergency vehicles and helicopters racing in the direction the girls had been walking and assumed the worst. 
  
 “It’s dangerous,” he said of the two-lane road, adding that he has seen many crashes there. “People come flying over the hill.” 
  
 Cecily Spallees, a personal care attendant at a group home near the crash site, also said drivers regularly speed on that stretch of road, which quickly changes from a 55-mph to 35-mph zone. 
  
 “I’m always telling one of my residents that he shouldn’t walk this strip at night,” said Spallees, adding that there are no streetlights in the area. “It’s not safe.” 
  
 Wisconsin State Patrol officials had the road and much of the surrounding land cordoned off Saturday night as investigators did their work. Along with Lake Hallie police, Chippewa County deputies and Chippewa Falls police were taking part in the investigation. 
  
 Several law enforcement vehicles were parked late Saturday at Treu’s home in Chippewa Falls, where investigators were combing through the house, garage and driveway. A tow truck was parked near the garage. 
  
 Residents of the area said on social media that they had seen police converge on the house a few hours after the crash, with Treu coming out to give himself up. 
  
 In a prepared statement Saturday night, Sokup wrote, “The Lake Hallie Police Department would like to extend our deepest sympathies to the families involved.” 
  
 A candlelight vigil will be held at 6 p.m. Sunday at Halmstad Elementary School. ||||| Breaking News Emails Get breaking news alerts and special reports. The news and stories that matter, delivered weekday mornings.

 Three girls were killed and a fourth was in critical condition Saturday after the driver of a pickup truck struck members of a Girl Scout troop who were picking up trash on the side of a Wisconsin road, police said. 
  
 A woman was also killed in the crash, which occurred about 11:41 a.m. on County Highway P in Lake Hallie, a village in Chippewa County northeast of Eau Claire. The Ford F-150 was traveling north when it crossed over a lane into the ditch, where it struck the group, Lake Hallie police Sgt. Daniel Sokup said. 
  
 The driver, identified as Colton Treu, 21, of Chippewa Falls, fled the scene but later turned himself in, police said. It was not immediately clear what charges he could face. A phone number for Treu could not immediately be found, and it was unclear whether he had an attorney. 
  
 "The Lake Hallie Police Department would like to extend our deepest sympathies to the families involved," Sokup said in a statement Saturday evening, adding that the investigation was continuing. 
  
 A relative of one of the uninjured girls told the Star-Tribune newspaper of Minneapolis that the children were area Girl Scouts in the fourth grade at Halmstad Elementary School in Chippewa Falls. 
  
 They were all wearing bright safety vests and were accompanied by several adults, the relative said. 
  
 A cause of the crash was not released by police. 
  
 In a statement on Facebook on Saturday evening, Chippewa Falls police called the accident a "truly horrific incident" and extended their condolences. 
  
 "Our thoughts and prayers go out to the families, friends, fellow students, fellow scouts and everyone else impacted by this," police said. "Truly, as a community, this affects everyone one of us. Something very precious has been lost and nothing can bring it back. We grieve with you." ||||| Emergency medical personnel gather at the scene of a hit-and-run accident Saturday, Nov. 3, 2018, in Lake Hallie, Wis., that killed two girls and an adult.

 LAKE HALLIE, Wis. (AP) — A pickup truck lurched off a road in western Wisconsin Saturday and hit a group of Girl Scouts picking up trash in a ditch, leaving three girls and one adult dead and critically injuring a fourth girl, police said. 
  
 Sgt. Daniel Sokup of the Lake Hallie Police Department said the driver of the black Ford F-150 pickup truck fled the scene but later turned himself in. He identified the driver as Colton Treu, 21, of Chippewa, Falls, Wisconsin. 
  
 Sokup said Treu will be charged with four counts of homicide through the negligent use of a vehicle. Sokup said the crash happened before a hill and there were no blind spots. 
  
 "The area is not an unsafe area," he said. Sokup said it was not immediately known if there were other factors that might have led the driver to leave the road. 
  
 The crash happened late Saturday morning as the girls were picking up litter in a ditch in Lake Hallie, a town about 95 miles (153 kilometers) east of Minneapolis. The pickup was heading north and crossed over a lane and went into the ditch, striking the group. 
  
 The girls were in the fourth grade at Halmstad Elementary School in Chippewa Falls, Wisconsin, the Minneapolis Star-Tribune quoted a relative of a girl in the troop who was not injured as saying. The Girl Scouts were all wearing bright safety vests and were accompanied by several adults. 
  
 Two of the girls and the woman were pronounced dead at the scene. A third Girl Scout was transported to a hospital where she later died, Sokup said. The fourth girl was transported to a hospital in critical condition. The names of the dead were not immediately released.

A:
It's another hard-to-fathom road accident involving kids. A pickup truck in rural Wisconsin veered off the road Saturday morning and struck a group of Girl Scouts and their chaperones who were picking up trash, reports the NBC News. Three fourth-graders and one adult woman were killed, and a fourth girl remains in critical condition, reports the Minneapolis Star-Tribune. Police say the driver fled but later surrendered. He has been identified as Colton Treu, 21, of Chippewa Falls, and Treu faces four counts of homicide through negligent use of a vehicle. Police aren't sure what caused the accident. They say Treu's black Ford F-150 came over a hill, crossed a lane, swerved into a ditch, and struck the girls, who were wearing bright safety vests. "The area is not an unsafe area," says a sergeant with the Lake Hallie Police Department, about 95 miles east of Minneapolis, per the AP. But a local resident disagrees. “It’s dangerous,” he tells the Star-Tribune of that stretch. “People come flying over the hill.” (Last week, a spate of accidents occurred at a near school bus stops.)
