Hopefully, this case is built on more than just circumstantial evidence.
LEO nailing down a motive will hold more weight.
150 pieces of evidence can be a clump of hair,
Grant it, some of Whites statements can be analysed and picked apart, showing some of his controlling/aggressive behavior but this is not enough to throw someone in prison.
Ironically, as it appears, she had died by his hands and his choice of words in one of his statements, he states he will take matters into his own hands.
"The distraught husband said Thursday night he was frustrated with the search and may take matters into his own hands."

Earlier on, when they first located the body, i read an brief blur, where a reported had seen the police removing a garbage bag with what looked dirt in the bag. This struck me odd, as a day or two earlier a neighbour commenting on how their family life was, stated the couple was seen often tending to their garden. Hours later for the life of me, i could not find that article mentioning the garbage bag.
I immediately, thought, maybe he had temporarily buried her in the backyard, until he could find a spot to dispose of her.
The location of their house is not conducive to effective surveillance and even if they tagged him early on in the investigation, he could have easily shook any surveillance within the small sidestreets and then the main roads would have been difficult to maintain a distance as they are fairly open.
I find it hard to believe, he formulated this whole plan in approximately 6 hours, killing her, disposing of the vehicle and disposing of the body and coming up with a plan for the next morning.
