TUCSON, Ariz. (AP) — A jury has have convicted former University of Arizona assistant track and field coach Craig Carter of aggravated assault and assault with a dangerous instrument against a female former student athlete he was accused of harassing, stalking and threatening.

Carter faces 15 to 23 years in prison when sentenced May 14 on his convictions Friday but he also awaits two additional trials.

The ex-coach did not testify during his trial but previously confessed to police that he choked the woman and threatened her with a blade when she said she wanted to leave Tucson.

Carter's attorney argued that Carter wasn't acting deliberately and that his client had lost control because the woman was ending their relationship.

Carter has claimed a relationship with the athlete was consensual, which prosecutors disputed.
