I'm confused by this scenario.
I thought she rented the car the morning of June 2nd. She'd spent the night with Matt and on June 3rd, saw Darryl, went to Salinas, got her hair dyed, got gas cans, and that evening, she called Ryan, told him she'd be there in the morning, which would be about 10am June 4th.
She then called Travis' number. I don't know if she reached Travis because the call was very short.
She filled up her gas cans and car and she left for Mesa, to arrive about 3-4am. Whether she slept in her car and saw Travis or whether Travis let her in the house at 4am, people still debate.
You are saying she rented the car June 3rd. I don't believe she told Ryan she'd drive straight through because she'd planned already to see Darryl, apparently his sister's baby, and Matt before going to Utah.
I'm guessing Ryan knew she was making stops along the way, so I don't know why she called him to confirm she'd be there by 10am. It makes no sense. I'll have to rehear his testimony, something I only listened to once because I didn't like his attitude. But this still makes no sense to me.
