Investigators searched Schnagl’s property in the days after she was reported missing – finding Jelinek’s purse, shoes and cell phone.

Investigators also discovered traces of blood in Schnagl’s home and car which have been sent to a lab for testing. But authorities say the amount of blood found doesn’t necessarily indicate any wrongdoing or any kind of struggle.

The documents also include comments from Jelinek’s family who claim that Schnagl was abusive in the past.
