In the probable cause section of the leaked search warrant, in the section where it discusses Erin's friend in TN and what she was told, it says that CL told Erin he was taking her hunting. I'm on my phone, or I'd link to a pdf of the warrant, but it is in context of what Erin told her friend...to paraphrase that section, CL was taking her on a surprise day trip, CL told Erin they were going about 2 hours away to an undisclosed location, CL told Erin they were going hunting.
From the probable cause statement - here is what her friend said - I changed her full name to JT.
JT, Erin's friend in Tennessee, confrmed Erin and Lee were romantically involved and Erin may be pregnant with Lee's child. Erin told JT that Lee was worried if his wife discovered Erin was pregnant, Lee's wife would divorce him and keep him from his child. JT knew Erin and Lee were going on a day trip together on 062814, for a celebration of Erin's pregnancy. JT forwarded text messages from Erin to support these claims. Lee told Erin they were going, to have a special day together and he would be taking Erin to an undisclosed location, approximately two hours from 29 Palms. Lee told Erin he was going to take her hunting.
