The brief video of the surveillance doesn't give us all there is. It cuts out when she walks south on S Vernon, past the white car. Based on google maps (which may be outdated) her car was a couple houses south of that on the other side of the street. Limited on-street parking there, may be by permit, idk.
Kierra was walking sort of north, towards her apartment, then turns south. She crosses the street at the home that is next door to her apartment building (the one with white urn flowerpots) and continues south....and that is all they showed.
I saved all the pics I could of the surveillance, and the corresponding google maps in the Case Archive.
