A 33-year-old Sioux Falls man is facing life in prison after being convicted of two counts of rape.
A jury found Mark Christians guilty of second and fourth degree rape this week.
Christians posed as a 15-year-old girl on a social networking site and struck up a friendship with another 15-year-old girl. About a year ago, he arranged to give her a ride to a party; instead Christians picked up the girl, took her to his house, gave her alcohol and raped her.
Christians faces up to life in prison because he is a habitual offender.
