According to the warrants, officers at the scene found a prescription bottle in Orduna's pocket and contacted the Ellis County Sheriff's Office in Texas.
The Garner Police Department requested that a deputy go to the address on the bottle in order to locate a member of the victim's family.
Orduna's mother, Susan Gasca, then contacted the Garner Police Department to confirm the name of her daughter. Police, along with the help of Gasca, were able to positively identify Orduna from markings on her body.
Gasca also told police her daughter recently moved to N.C. with some friends she met while in Marine boot camp.
Shortly after police spoke to Gasca, they say Spencer Bolick filed a missing person report for Orduna, who he said was his girlfriend and his roommate.
Bolick said Orduna had been living with him for a few weeks.
He went on to say the two were smoking marijuana and drinking that night at his apartment before getting into a fight.
According to the warrants, the couple then left in Bolick's car.
Bolick told police he was driving down Aversboro Road when Orduna "jumped out of the moving vehicle."
Instead of stopping, he said he returned to his apartment and told several people what happened.
Bolick said he then sent a sober friend back to the area where Orduna allegedly jumped from his car. That person, who police have not identified, called 911 from the scene.
