Timothy Dean has been found guilty in the deaths of Joshua Niles and Amber Washburn. A jury deliberated for just over four hours. The former Texas police chief was found guilty of first-degree murder, second-degree murder and second-degree conspiracy in the death of Joshua Niles. He was found guilty of second-degree murder in the death of Amber Washburn. He was also found guilty on two counts of criminal possession of a weapon. Dean's wife and co-defendant, Charlene Childers testified against him. She said she and Dean plotted to kill Niles, her ex-boyfriend, after she lost custody of their children. Prosecutors said Dean gunned down the young couple in the driveway of their Sodus home back in October of 2018. Dean shot Niles 10 times and Washburn once in the head, killing them both. Childers accepted a plea deal which reduced her second-degree murder charge to first-degree manslaughter, a felony, Wayne County Assistant District Attorney Christine Callanan said. Childers also pleaded guilty to second-degree criminal possession of a weapon, a felony.
