Source: Neighbors in a Meridian subdivision are still trying to understand and cope with a deadly accident that took the life of a young boy on Thursday. Ada County Coroner Erwin L. Sonnenberg says 10-year-old William Passero was pronounced dead at a local hospital at 12:12 p.m. on Thursday. Sonnenberg says Passero died of blunt-force trauma. Police say the boyCo was riding his bicycle in a crosswalk around 11:30 a.m. when he was hit by an SUV and fatally injured. The accident happened in the Lochsa Falls Subdivision in Meridian at the intersection of Horse Loop Circle and Goddard Street. Officers say the boy's bike was found 30-feet away from where he was hit. Chief Deputy Tracy Basterrechea told KTVB the collision happened when a 70-year-old woman driving a 2005 Nissan Xterra was exiting a roundabout in the subdivision. Basterrechea says the boy was not wearing a helmet when she struck him. Several witnesses tell KTVB the boy's mother was near the intersection at the time of the crash. They say she was screaming, and immediately yelled for neighbors to call 9-1-1. Police report that emergency responders were on the scene a short time later, and that paramedics took the boy to the hospital where he was pronounced dead. Tyler Ashton was driving behind the SUV when it hit the young boy. Though he didn't directly witness the accident, Ashton told KTVB the accident was "gruesome," and that he immediatley knew the ten-year-old was seriously injured. Ashton said the SUV's driver was horrified. "She was obviously pretty scared, didn't really know what to do," said Ashton. " You could see it in her eyes. She was pretty shaken up and panicking. It was not something you really like to see." Police investigators spent several hours at the scene doing their best to reconstruct what exactly happened. Several neighbors KTVB spoke to said they'd seen plenty of close calls involving vehicles in the same area of the subdivision due to heavy landscaping. Witnesses and people who live in the neighborhood say they believe that landscaping could be part of the problem. "I think it's hard for them to see kids crossing just because of the bushes and stuff," said Ashton. Meridian Police believe the 70-year-old woman was going around 25 miles-per-hour when the crash happened. Deputy Chief Tracy Basterrechea says he doesn't have any reason to believe speed was a factor in the accident. Police have not charged the driver with any crime. Prosecutors will decide whether or not to press charges when the accident is fully investigated, which could take several weeks. "Obviously this is hard on everybody -- the driver of the vehicle and the family of the child -- and people need to keep that in mind before they pass any judgment on any of this," Basterrechea said.
