The Dallas County Medical Examiner's Office says Shavon Randle, the 13-year-old Lancaster girl whose body was found early Sunday following an Amber Alert, died from gunshot wounds.
In a report released Friday, the medical examiner says Randle's manner of death was homicide.
Randle was reported missing Wednesday, June 28, from a home in the 1300 block of Southridge Drive.
Police issued an Amber Alert that day, indicating she may be in grave or immediate danger.
Police said she was taken from her home by an unknown man who they said later called a member of the girl's family.
"They confirmed that they knew who the victim was and they said, 'Well, we have her,'" Lancaster Police Department Det. Joseph Brickett said. "Then they called back later on the victim's cell phone and said, 'If you call law enforcement, then we'll harm her.'"
Brickett said investigators were able to trace Randle's cell phone location for a while before it was turned off.
Early Sunday, police were led to an abandoned home in the 2200 block of Kiest Boulevard just before 3 a.m. after receiving tips.
In addition to Randle's body, police also found the body of 19-year-old Michael Titus, who was initially named as a person of interest in the girl's disappearance.
Titus's death has also been ruled a homicide from a gunshot wound, officials said this week.
Five people are in custody facing a variety of charges related to Randle's disappearance, but as of Friday afternoon none is charged in the deaths of Randle or Titus.
A growing memorial of flowers, balloons and teddy bears has been set up outside the home where their bodies were discovered.
