To reiterate, Adam saw Jonah earlier in 2011 in Scottsdale, AZ. Then day after Max's accident, on 7/12/11, Adam flew to Coronado and Rebecca picked him up at airport. She drove him to the hospital, and Adam met with his brother Jonah. Then IIRC, they all drove to a McDonald's to eat dinner and met up with Dr. Luber there too. Altogether Adam, Jonah, Rebecca and Dr. Luber were at McDonald's eating. Then Dr. Luber drove Jonah to hospital or Ronald McDonald House and Rebecca drove Adam and herself to Spreckel's mansion and Rebecca went to main house while Adam went to guesthouse in back.
Adam states he saw Rebecca hanging off outdoor courtyard balcony as he awoke and was going to main house for breakfast. He said he went into kitchen to get knife to cut her down. He also said he stood on three-legged lawn table to cut her down.
According to Cynic's drawings, Adam was tall enough to cut her down without stepping atop a table...
Adam stated he then call 911 at 6am. While on 911, he stated he also texted his brother Jonah that Rebecca had hung herself...
Suspicious? Yes.
