SALT LAKE CITY (AP) — Utah prosecutors are dropping charges against a man accused of automobile homicide and other crimes in a Aug. 17 crash that killed a woman and her 16-year-old daughter sleeping in their parked truck in Big Cottonwood Canyon. KSL-TV reports that the Salt Lake City County District Attorney’s Office dismissed charges filed in October against Manases Castillo of Layton. The office says in a statement that it believed when it filed the charges that Castillo was responsible for the crash. However, the office says new information now indicates otherwise and that another person will be charged soon. Brandilee Chacon  and her daughter Sierra were sleeping when another vehicle went off a road and crashed into their truck.
