An Eau Claire man is going to prison for 15 years as the result of a plea agreement connected to accusations he sexually assaulted two young girls. Dustin Titera was sentenced Friday. Prosecutors told the court the victims were about five or six years old when the assaults started. They continued for several years. The girls told investigators Titera would have them touch him inappropriately. The assault charges were dismissed and he pleaded guilty to a charge of causing mental harm to a child.
