Sorta OT, but isn't it strange that, after someone is killed while committing a serious crime, there is always a family member, fiancee, friend, whatever, saying that the deceased was "turning their life around" and "his future was looking bright"?
In reading the article, I noticed several glaring mistakes the beauty queen and her fiance made. He brags about her $60,000 engagement ring, they try to pay for pizza with $100 bills(!!), and they allow visitors at all hours. Those factors, combined, equate to gross stupidity in this day and age. They made themselves into targets and it was just a matter of time before someone took a stab at them.
FWIW, they are more of a target after the publication of this story than they were before. Were I in their shoes, I would seriously consider moving.
And I fully agree with 4angrybadgers; do not knock on my door after nine at night or before nine in the morning unless you want to be rather rudely greeted.
