Reward upped, more video released in officer death

Police in Philadelphia have released a second surveillance tape of the men they believe gunned down an off-duty officer during a robbery and upped the reward in the case to $118,000 as they try to track down the killers.

The new footage released Tuesday shows the same two men police believe killed Officer Moses Walker Jr. after he finished his shift early Saturday morning.
Walker was in street clothes but still carrying his service weapon when he was fatally shot. The footage appears to show Walker glancing over his shoulder at the two men walking behind him a few minutes before he was shot.

Police believe Walker’s assailants announced a robbery then one of them shot him three times in the chest when he drew his weapon.
