DODGE CITY, Kan. - A former Dodge City police officer has been found guilty for the second time in the death of his ex-girlfriend. A Ford County jury on Tuesday found Christopher Tahah guilty of first-degree murder in the 2007 shooting death of Erin Jones in Dodge City. The 25-year-old mother of two was killed in her home by a shot fired from outside. Tahah was first convicted in 2008 of first-degree murder in Jones' death. The Kansas Supreme Court threw out the conviction last year, saying the jury should have been allowed to consider lesser charges, including involuntary manslaughter. The Dodge City Globe reports (http://bit.ly/NZcOnJ ) no sentencing date was set.
