Michelle Le's case was on Dateline Saturday night. She went missing from Hayward, CA., I won't give all the details, but wanted to point out a few things about the investigation in her case.
Michelle went missing May 27th. LE found her car within a day or two. Her body was found September 17th. LE did not share
anything with her family or media until after they arrested her friend Giselle Esteban for her murder. LE focused on Esteban fairly quickly. Some of the evidence they had;
- Cell phone pings
- Esteban's hair in Michelle's car
- Drop of Michelle's blood on Esteban's shoe
- Video surveillance footage of Esteban at Michelle's work
- Witness testimony from a man Esteban thought Michelle stole from her/ruined their relationship
Michelle's cell pings were similar to Esteban's. In other words, the phones were obviously together the night Michelle disappeared, then her phone shut off. Also, it took three months for results from the evidence sent to the FBI lab to be returned.
My point (sorry for droning on). LE was developing all this evidence, and for four months it appeared they had nothing. This gives me hope in Erin's case, the same thing is occurring. SBSO has cell phone data, and are searching the triangulation areas. Which by the way, is how Carrie McGonigle found Michelle's body (that's an amazing story in its own right)
