Jose Holmes Jr. testified Wednesday that he already was wounded and lying on the ground when somebody leaned over a concrete barrier on the Danziger Bridge and shot him twice in the stomach.

Holmes, who is expected to return to the witness stand Thursday for cross-examination by defense attorneys, said he didn’t know police were shooting at him, a friend and several relatives as they tried to cross the bridge in search of food less than a week after the devastating 2005 storm. He said officers didn’t identify themselves or issue any warnings before they opened fire.
