Father's death 'motive' for Oklahoma shooting rampage

The explanation for a shooting rampage that terrorised a black neighbourhood in the US state of Oklahoma and left three people dead may lie in a killing that took place more than two years ago, it has been revealed.

Carl England, whose son is accused of the weekend shooting spree in Tulsa, was fatally shot in 2010 by a man who had threatened his daughter and tried to kick in the door of her home.
