Mora allegedly kidnapped the girls earlier that evening after being at a residence with them and an unidentified adult male at a home in Phoenix. Fox10 reports the girls' mother was also at the home. At some point during the evening, the sisters, Mora and the man were getting ready to drive to a local convenience store when the man went back inside the home. That's when Mora allegedly jumped into the driver's seat and drove off with the sisters in the backseat. When the unidentified man tried to stop Mora from leaving, Mora allegedly hit him with the car. Phoenix Police Department Family were able to call the girls but only heard screaming before the call was disconnected. The Phoenix Police Department responded to the residence and began their investigation into the kidnapping. The family told Fox10 the girls were inseparable. "The minute Hayli was responsive, she was asking about her sister," Briana Campos said. "They did everything together...They went to school together. They liked being around each other. You’re gonna have love for a sibling, but they were the closest in age." The investigation remains ongoing. Mora has been booked into Maricopa County Jail on charges of first-degree murder, aggravated assault, kidnapping and car theft. Attorney information was not available Monday.
