The jury trial for a Casper resident charged with sexually assaulting a 10-year-old girl began Monday. Miguel Martinez faces one count of first-degree sexual abuse of a minor and one count of second-degree sexual abuse of a minor. If found guilty, Martinez could face up to 70 years in prison. The girl said Martinez, who is a family friend, invited her into the bathroom, touched her breasts and genitalia before penetrating her. Nurses at the Wyoming Medical Center completed a sexual assault exam and found redness and abrasions on the girl’s genitalia.
