I see there is a very, very lengthy amount of comments for this case.
If it has not been mentioned already, I would like to discuss a case that has some similarities and what the motivation for it was in the end.
Vern Holbrook.
He was an older man that was known to be an extremely hard working real estate agent. Basically, family and real estate was his life.
He was scheduled to show a house to a Hispanic couple, and was attacked when he arrived.
His coworker found him, and he had been stabbed with his throat slashed. He eventually died from the attack.
The caller for Vern was later traced back to the Hispanic woman of the couple.
When the plot fully unfolded, Vern's ex business partner had co-conspired with his son's ex-wife (who Vern supported financially and helped her out despite her being divorced from his son).
The Hispanic couple was living in a hotel room financed by Vern's ex business partner. Vern's ex business partner had also made some scheme to pay for Vern's life insurance payments on behalf of the company they worked for.
MUCH of the case and trial was circumstantial but the ex-business partner went to prison anyways.
TL;DR version: A man was attacked by a Hispanic couple when they posed as buyers for a house. His ex-business partner and ex-daughter in law financed the entire scheme.
