Plea agreements and prison terms wrap up prosecution of a trio charged in a violent home invasion robbery incident in Bullhead City. Authorities allege that Santa Lujan, 23, is the mastermind of the plot that pitted she and her friends against her roommates. Police allege that Lujan had two friends enter her home in the 1600 block of Lynn Drive after she and her roommates went to bed on July 4, 2013. Police spokeswoman Emily Fromelt said the friends, Josh Saddler, 25, and Brandon Harcourt, 21, were dressed in black and wore ski masks when they entered the residence and tied up Lujan in a bedroom to make it appear as if she were a victim. Saddler allegedly struck one of Lujan’s sleeping roommates in the head with a baseball bat. The 21 year-old man suffered a fractured skull. Saddler and Harcourt allegedly fled the home after collecting electronic devices that were later sold for cash with some of the money given to Lujan. Saddler was convicted of aggravated assault and burglary and sentenced to 12 years in prison. Harcourt was sent to prison for four years after pleading guilty to burglary.
