Rightly or wrongly the State are holding off on arresting WA until after DAs trial and conviction. Her conviction makes the case against WA infinitely stronger, simply because it would be extremely unlikely that CA and DA would conspire to kill DA without WA's knowledge and approval. Obviously that's not going to be enough to convict WA, the State needs strong evidence, but DA's conviction gives them an upper hand in WA's trial.
I think the State also has lots more evidence that incriminates WA that they have not released and also more evidence that will be produced as they continue with pulling data from the various electronic devices, this can take months. There will be a number of witness depositions in August as well which will strengthen their case e.g deposition of Sara Yousef who went to the University of Miami and then severed ties with WA for unknown personal issues. The State aren't taking her deposition because Wendi called her fat, it will be something significant and relating to DM's murder.
Other incriminating evidence that I think will be forthcoming that will further incriminate WA:
- OK Cupid data showing WA intended to move to Miami before DM was killed
- lunch dates testimony detailing WA's state of mind, presumably she was all over the place
- Geek squad testimony. He would have told WA within 1 minute of seeing the TV it could not be repaired. They did not have the parts to repair cheap TVs as it was not economically viable. However he remained there for 40 minutes.
- DA was an obsessive note taker and organiser, I believe there will be something in her notebooks and devices that shows WA was planning to move to Miami pre-murder e.g google searches for schools
- WA's cellbrighted phone. New tech developed feb 2024 allowed LE to do much deeper data recovery on phones.
- WA's WhatsApp data. In 2016, on the day of the bump, CA admitted he had been messaging WA all day on WhatsApp. Yet when WA was on the stand in the various trials she played dumb when asked about WhatsApp, unsure of her history with the app. If she was a prodigious WhatsApp user in 2016, then the likelihood she would have been in 2014.
