( CNN ) -- Prosecutors in Ohio began presenting evidence to a grand jury on Monday in the August 5 death of Cincinnati man John Crawford III , shot and killed by police while carrying an air rifle in a Walmart store . Police contend that Crawford , 22 , was `` waving a rifle-type weapon at customers , including children , '' according to statement from Beavercreek Police Capt . Eric Grile . Michael Wright , who is representing Crawford 's family , says Crawford picked up an unwrapped air rifle from a shelf inside the store in Beavercreek and was talking on the phone when he was confronted by police . Witness Ronald Ritchie called 911 to report `` a gentleman walking around with a gun in the store , '' according to a recording of the call . Ritchie , who can be heard in 911 recordings released by the Beavercreek police department after the incident , says that a man was carrying what appeared to be a rifle , pointing it at people and `` waving it back and forth . '' Then , there are muffled screams heard on the 911 tape , and Ritchie says he heard gunshots in the store . According to police , Crawford did not comply with police commands to drop the weapon . Crawford died shortly after being transported to a nearby hospital . His death was ruled a homicide by gunshot wound to the torso , according to the local coroner 's office . `` The quick response [ by police ] was instrumental in containing this situation and minimizing risks to customers , '' Grile said in a statement at the time . The Ohio attorney general 's office , which conducted the investigation into Crawford 's death , has kept all details of its investigation under wraps pending the grand jury reviewing evidence and deciding whether charges should be filed . Surveillance video from inside the store has not been released to the public . `` Because it is an ongoing investigation , we have not released the video , '' Walmart spokesman Brian Nick told CNN . Two police officers -- Sgt . David Darkow and Officer Sean Williams -- were placed on paid administrative leave after the shooting but Darkow has returned to active duty , according to Beavercreek city attorney Stephen McHugh . The grand jury proceedings are expected to last several days , according to Hamilton County prosecutors , who are leading the team that is presenting evidence to the Greene County panel . Beavercreek , where the incident occurred , is in Greene County outside Dayton . `` After all the evidence is presented , we would like to see an indictment handed down on the police officers , '' Crawford family attorney Wright told CNN . Wright has continued to push for the public release of Walmart surveillance video from the incident , but law enforcement officials have asked the store not to release it publicly , Walmart spokesman Nick said . `` We are deeply saddened about the loss of life that occurred , '' Nick added . `` Our thoughts and prayers are with the family and loved ones of those involved . '' Crawford was a high school graduate and father of two , according to his father , John Crawford Jr. , who addressed the press shortly after his son 's death . `` My son was not a monster . He was a loving father , he was a loving son , '' the elder Crawford said . Wright said that both the victim 's father and his mother , Tressa Sherrod were scheduled to testify before the grand jury on Monday . The grand jury proceedings are expected to last several days , according to a statement by Hamilton County prosecutors . CNN 's Jason Carroll contributed to this report .
