Police say Ouellette put her back in the truck and drove her to her home, where her family sought emergency medical help. Sophie was pronounced dead at a hospital at 12:51 a.m. on May 21. An autopsy determined that she died from blunt-force trauma to her torso. ► Support East Idaho News: https://www.eastidahonews.com/donate/ ► Subscribe to East Idaho News: https://www.youtube.com/c/Eastidahone... ► Subscribe to Courtroom Insider:    / @courtroom.insider   ► Get merch: https://www.eastidahonews.com/shop/ ► Download our free app: http://marketplace-redirect.doapps.co... ► Like East Idaho News on Facebook:   / eastidahonews   ► Like Courtroom Insider on Facebook:   / courtinsider   ► Follow East Idaho News on X:   / eastidnews   ► Follow Courtroom Insider on X: https://x.com/courtroominside ► Follow us on Instagram:   / eastidahonews   ► Subscribe to our free newsletter: https://www.eastidahonews.com/newslet...
