By Fiona Roberts Last updated at 2:11 PM on 16th July 2011 A Mormon teenager will stand trial for allegedly helping her lover to kill his 16-year-old ex-girlfriend, a judge has ruled. Toni Fratto, 19, and Kody Patten, 18, are accused of hitting Micaela Costanzo over the head with a shovel, cutting her throat and then burying her body in a shallow grave just outside West Wendover, Nevada. Prosecutors claim the couple, who were planning to get married, murdered Micaela because she had been texting Patten asking to get back together with him.

Young couple 'drove to swimming pool to clean up after killing' - then went to McDonald's

16-year-old was murdered 'because she tried to get back together with ex-boyfriend'
Fratto told lawyers Patten picked her and @placeholder up and then drove out of town because Micaela, described as a popular student, 'didn't want anyone to see us or anything.'
@placeholder got out and saw the 16-year-old lying on the ground.
He also said @placeholder's father drove Fratto to his lawyer's office to make her confession when her parents were out of town, as he knew they didn't want her to speak to an attorney without them being present.
