Thinking on why PPD and the DA released the warrant early. They don't have to put EVERYTHING they have in the affadavit. Just enough to get an arrest. They may have more. So they toss what they have out there to let EA (and an accessory after the fact?) know what they have. The events and timeline in that warrant may hold more for someone involved than it does for us speculating on here. IOW, such an individual might say to themself, "Ah, if they have 'A', then is it a good chance that LE has 'B' and maybe 'C'? Will they be coming to my door next?"
Someone out there MAY know something that helps connect the dots. By LE showing what they've got already, this may push that someone in a positive direction. It also may lead someone to realize something they saw in the early morning hours holds more significance than they thought and call in a tip. We still have the damage to EA's car - where did that occur? how did it occur? when did it occur? Knowing those answers may help connect the dots.
