LE says this was, at first, an attempted robbery.
I wonder if it escalated to murder due to the following line of "thought" by the perpetrators:
- The victims maintained a modest life style. It is highly likely that their home, though valuable, was not large. Rather, it was valuable due to location and charm.
- Though she is a physician, her practice is family medicine, not more lucrative specialties and not elective plastic surgery "bump ups". She gives back by practicing medicine at a community clinic- not exactly the stopping place for Madison residents with good insurance featuring quick payment and high maximums.
- Their modest philosophy is continued with their choice of cars (one was VW van). The available photo depicts a person(s) happy at giving back- no power wardrobe and no expensive jewelry.
- In KS' world, even relative affluence is synonymous with bling jewelry, "large" cars of prestige brands, rolls of flash cash, and a huge home crammed full of the latest over the top gadgetry.
- As none of this is evident in the victims, M needs to assure KS that the victims really are wealthy- in fact, they have "bands of cash" on hand at all times.
- KS and his accomplice then initiate a home invasion robbery in search of the fabled "bands of cash". Surely there is bling jewelry and high end fire arms hidden in the house as well. Don't all affluent people have these things?
- KS and the accomplice only find more modesty. In a rage, they feel that the victims are 'holding out". A kidnapping is initiated to drain the bank accounts via ATM machines. This plan is then abandoned as too risky due to cameras etc. The victims are then murdered.
