( CNN ) A man identified as Terence Walker is seen in a police body-camera video bolting from a Muskogee , Oklahoma , officer who felt a weapon after a pat down . Officer Chansey McMillin gave chase , his body-cam capturing his shadow as he trailed the suspect in the afternoon light of January 17 . Walker , 21 , is seen stopping suddenly and bending down to pick up something he dropped on the road . A white car approaches . The graphic video shows McMillin pulling his pistol , taking aim and unloading five shots . Walker turned around , then started running . He was struck three times , police said . In the video , Walker is seen as he tumbles to the ground , then rolls into a ditch . He died at the scene . Later , the video shows an emotional McMillin leaning against a police car . `` Why did ( Walker ) have to do that ? '' he asked as other officers comforted him . Since Ferguson , Missouri , teen Michael Brown 's death prompted a national move to put body cameras on all America 's police officers , scenes like the one captured in the body-cam video from Muskogee will likely become more common . President Barack Obama recently announced a $ 263 million package to help local police departments buy 50,000 cameras . The New York Police Department , the nation 's largest , launched a pilot body-camera program in December . In Muskogee , about 50 of its 88 police officers started wearing body cameras in November , according to department spokesman Sgt . Michael Mahan . The January 17 incident outside Old Agency Baptist Church is the first officer-involved shooting captured by a body camera . The video was released Friday after the department showed it to Walker 's family and local leaders in an attempt to quell tensions in the community , Mahan said . `` We 've seen a lot of departments have a bunker mentality and sort of enclose themselves and not be real open with the public , '' he said . `` We 're trying to set a precedent . We think this does n't allow any speculation to foster within the community and lets all the facts come out . '' The encounter began with McMillin approaching Walker outside the church and patting him down . `` Relax , '' the officer is heard saying in the video moments before Walker takes off running . `` What are you shaking for ? '' Mahan said witnesses told police that on the day of the shooting , Walker had threatened his ex-girlfriend , who was attending a wedding at the church that day . Mahan said Walker allegedly told his ex that he `` had a bullet with her name on it . '' Moments after the shooting , a man who identified himself as the church 's pastor is seen in the video approaching the officer and saying : `` Do n't shoot no more . '' McMillin ordered the pastor to stand back . The officer can be heard on his radio calling for an ambulance . Another officer checked on Walker and picked up something off the ground and tossed it away from the suspect . McMillin is heard saying it 's a handgun ; another officer said the weapon was loaded . One officer checked Walker 's pulse . The pastor is seen in the video telling other officers that McMillin `` did everything right . '' The investigation is being handled by the Oklahoma Bureau of Investigation . McMillin is on paid administrative leave , Mahan said . It was his second officer-involved shooting in six months . The officer was cleared in the July shooting of a suspect who attacked a man with a knife , according to Mahan . The officer opened fire after the knife-wielding man moved toward him . The suspect survived . Mahan defended the video 's release . `` What we 're trying to do is to set a standard for the nation and say that we believe that openness and transparency is the best policy , '' he said .
