8. Robert William Fisher
If there was ever a competition of becoming a family-murderer, Yaser Abdel Said and Robert William Fisher would have been racing wheel to wheel. While Yaser allegedly killed his two daughters, for Robert it was his wife and two children.
In 2001, a house in Arizona was ripped off by natural gas explosion. A woman and her two children were found dead lying in bed inside the house. But investigation led to a conclusion that the explosion was not an accident. Someone pulled out the gas line, lit a candle, and then physics took over.
And autopsy report revealed the truth that those victims did not die because of the fire. The woman was shot in the back of the head. And the children’s throats were slashed.
The only question left was: where is the father?
Robert went missing at that time, presumably hours before the house exploded. He has never been found or even spotted ever since. And FBI is offering a reward up to $100,000 for any information directly leading to the arrest of one of their top ten most wanted fugitives.
