Federal prosecutors secured their biggest victory yet on Tuesday in their crusade against the violent Bounty Hunter Blood Gang, which operated throughout South Hampton Roads, including in Suffolk.

Xavier Rondell Davis II, 21, of Norfolk, pled guilty in Norfolk’s Federal District Court to taking part in a gang assault that left one man dead and two others seriously injured.

“This was a savage, senseless murder by Bounty Hunter Blood gang members,” U.S. Attorney Neil H. MacBride said in a press release announcing the plea. “This conviction — after more than four years since this brutal attack — is a testament to law enforcement’s commitment to bring justice to the family of those attacked that fateful day.”

According to court records, on July 27, 2007, about a dozen Bounty Hunter Blood members, including Davis, lured three victims to a parking lot in Ocean View, where Davis ordered them to the ground at gunpoint and demanded their money and valuables.

The victims were then beaten and kicked until gang members fled after hearing that police were on their way. Two of the men escaped before Davis and another gang member returned to continue beating the unconscious third victim, 19-year-old James Robertson, the records state.

Robertson died of blunt force trauma to the head shortly after arriving at Sentara Norfolk General Hospital.

Davis pled guilty to one count of murder through the use of a firearm and two counts of assault with a dangerous weapon in aid of racketeering activity. He will be sentenced to an agreed-upon 35 years in March.

His charges are the most serious to spring from an investigation that snared numerous members of the gang, including two from Suffolk. So far, all have pled guilty.
