The trial began Tuesday in a social media case that has garnered national attention.
Two Saugus, Massachusetts, residents are accused of sexually assaulting a 16-year-old girl and capturing it on the social media app Snapchat.
On Tuesday, someone who saw those disturbing videos took the stand in Salem District Court.
What happened in the woods behind Waybright Elementary School in Saugus is what the two sides are arguing. And the snapchat videos will be key. The only problem is that videos on Snapchat disappear as soon as you play them.
Michelle Enos of Saugus took the stand Tuesday and described the four graphic videos she says her daughter received via Snapchat showing the alleged sexual assault.
Those videos that her daughter showed her back in September of 2014 are what led police to the victim. The 16-year-old was later found in the woods partially naked, alone and under the influence of drugs.
"We were watching TV and the videos started coming in and (my daughter) jumped up at that point and showed me the videos and immediately we called the cops," Enos said in court Tuesday.
The latest news from around the state
Rashad Deihim, 21, and Kailyn Bonia, 20, are both facing a number of charges, including assault to rape and kidnapping. They say the sex was consensual.
Prosecutors, however, argue that the victim was too imparied to give consent. The first witnesses on Tuesday - Saugus police officers - said the victim could barely speak and was curled up in the fetal position.
The Snapchat videos will be evidence, but only still images taken before the video disappeared in the app. They are screenshots that leave plenty of room for both sides to make their own interpretations.
Two others have already pleaded out in this case, including a teenager who admitted recording the Snapchat video.
