( CNN ) -- Within seconds after the shooting began , at least one man who was grazed by a bullet grabbed the gunman , a middle-aged woman snatched ammunition away from him , and a group of people held him down while another man grabbed the gun out of his hand , a man and a woman who helped subdue the shooter told CNN Sunday . `` It was so surreal . You do n't believe what 's really happening in front of you . People are really dying , '' said Joe Zamudio , one of the people who helped restrain the suspect . `` As the police took him away , I looked up and it was just -- it hit me like a ton of bricks . All these people that were wounded , and all these people 's lives were changed in an instant . '' Zamudio had been inside a nearby Walgreens when he heard the shots ring out . `` I ran outside towards the shots and when I rounded the corner , the first thing I saw was the people wrestling with the gunman . Behind that it was just kind of like people laying everywhere and kind of falling and crawling . Kind of realizing you had been shot is a weird thing to go through , I think . The people did n't really know . They were saying , 'What happened ? What was that ? ' And then it started , a lot of ' I 'm bleeding . ' Like , this is real -- this is real . And then it was just , you know , 'Where 's the ambulances ? ' It was just like nobody really knew what was going on . Nobody could really come to terms with it for minutes it seemed like . Nobody really kind of realized the massiveness of what happened . '' `` What really scared me , '' Zamudio said , was seeing a middle-aged , `` maybe elderly woman , '' wrestling the next magazine away from the gunman . `` I realized he was trying to reload his gun ... I just kind of fell on him too , like kind of put my weight over him , and made sure the gun was down and out of play . '' The woman was Patricia Maisch , who said she did n't have time to think about what she was doing . `` He ( the suspect ) pulled the magazine out of his pants pocket and it dropped onto the sidewalk . And before he could reach it , I got it , '' she said . `` I just reacted . I did n't have an opportunity to think . '' Maisch brushed off reports of her being called a hero . `` The two men that secured him were the heroes . I just was an assistant in being able to get that magazine or clip , '' she said , humbly . The gunman was already on the ground when Zamudio got there , he said . `` I laid on him and held him down , and made sure the gun was down . '' The `` real hero , '' Zamudio said , was the man who grabbed the gunman first . `` There was a gentleman who was wounded on top of the head , I think he got hit with a ricochet or something , ( a ) bullet grazed the top of his head , '' but still he `` initiated the contact '' with the shooter . `` Then other people were able to grab on and they were able to kind of contain him and pull him down . '' Zamudio 's account differs slightly from Maisch 's in that she said two men secured the suspect . A third man wrestled the gun out of the shooter 's hand , Zamudio said . In the confusion , Zamudio explained , he grabbed that man 's wrist at one point , not knowing who it was . `` He says to me , 'No , no , it 's him , it 's him . Just put it ( the gun ) on the ground . Put it on the ground . '' It felt like three or four minutes before the police came , Zamudio said . `` I thought it seemed like forever . But I think when you 're in the moment , your perception of time is off . ''
