I have heard attorneys say this for years:
"You never know what a jury is going to do."
It's so very true. No matter how careful the attorneys are during jury selection, a whacko can easily slip by. With CSI on TV an other shows, people think they "know" how this all works. Some jurors go into these trials EXPECTING the "CSI" type smoking gun. They want to see DNA, a video tape of the actual murder, etc. if they don't, they are voting not-guilty.
I believe if they present this case in a way that shows SL being a liar, a cheater, a manipulator, a user & a controlling, abusive husband (to both wives) this will set the stage. Then they need to move on to how he easily lives a double life by lying about working/not working. Being a "good dad & loving his children / yet refusing to pay child support and stealing his son's dog. Having a $1.1M life insurance policy on his 23 yo stay at home wife. Making that premium payment rather than paying child support. Taking out a credit card for a cruise and never making a payment. Build this all up to these supposed "stalking incidents" This way it is clear in the juror's minds that Melinda had been controlled and pretty much been held captive in that house for the last 5 years. This way the idea of a "stalker" suddenly coming back from her past sounds even more obsurd.
