PRINEVILLE, OR -- A Prineville man is accused of abusing his babies. 

Prineville Police started investigating 26-year-old Justin Viescas in July, after the 43-day-old twins were treated at the hospital for multiple fractures. Doctors believe the injuries were caused by non-accidental trauma. 

Viescas was indicted by a Grand Jury and arrested Wednesday on two counts of third-degree Assault, and two counts of Criminal Mistreatment in the first degree. He has since posted bail and was released. Anyone with information in the case is asked to contact Detective Kathryn Bottoms at 541-447-4168, or via email.
