That's right Gardener they do not use DNA but skull features to know she was Asian. Yes Shiressleuth there is a resemblance, the weight and height were also on target, However.
i,e, The Natalie Bollinger case: she went missing Dec 28,
December 29 her father Ted Bollinger posted on the fox news channel website: My daughter was murdered I just left the Sheriff's office. "SO the father made it known before LE"
January 2 LE officially confirmed the body found was Natalie Bollinger and it went to the news sources.
My point being is they go to the family first, her handbag could have been there with her name and other identifying things, the father was called in they may have showed him the items he said yes its my daughters items and showed him photos of his daughter. Yes LE can miss things but it would be pretty lame for them to miss a girl Jenna that recently disappeared from 20 miles away. I would bet dollars to donuts they brought a photo of the UID female found at the mall to Jenna's parents (even though she was determined Asian because they could be wrong) and they said "No its not her", and went to other family members of the missing, before they went public with a sketch of an unknown girl.
