SIOUX CITY, Iowa (AP) – Prosecutors have dismissed their case against a Sioux City father of a 5-month-old who suffered a skull fracture, but the boy’s mother is still charged. The Sioux City Journal reports that Woodbury County Attorney Patrick Jennings said Friday in his motion to dismiss the case that it was unclear whether Aaron Tucker was at fault. Jennings says the case can be refiled if more evidence surfaces.

The boy’s mother, 25-year-old Kara Jackson is charged with child endangerment resulting in serious injury. Her arraignment is set for Monday. According to court documents, Tucker and Jackson accused one another of dropping the child on several occasions.
