From the PC, in case you missed it:
Zoe was making a trip to Walgreens to return a Redbox movie at approximately 4:45 on Sunday. This matches what her parents told the police and it was also implied that other evidence backs this story up.
DPD is looking to speak with anyone that was at the Walgreens at Garland Road and Peavy between 4:30 - 5:00.
DPD canvassed area homes and businesses today to question and obtain surveillance footage.
The family is asking the public to meet tomorrow to canvas the area of the crime. They are meeting at Norbuck (sp?) park at 5 PM.
The person who originally found Zoe and alerted the motorist has been identified and questioned. They are not a person of interest. DPD believes that the person feared being arrested due to open warrants, which is why they left the scene.
When question time came, it was hard to hear the questions being asked, but I thought I heard one asking about if the crime was believed to be random. The officer did not answer directly, but he did say that he encourages the public to be diligent about watching their surroundings in public.
This was the speaker at the press conference:
