Witnesses took the stand on Tuesday in the murder trial of former TikTok star Ali Abulaban who is charged in the shooting deaths of his wife, 28-year-old Ana Abulaban and 29-year-old Rayburn Cardenas Barron. Prosecutors played a TikTok video in court showing Abulaban broadcast live on social media from the apartment he shared with Ana while she was on the phone with police in the months leading up to her death. Ana's best friend Julia Stunze testified that three months before her murder, she saw injuries on Ana's face.
