Police chief bill citty knows it well. Theres a lot of gang activity. Its a lowerincome area and there has been, in the past, a lot of crime in that area. I am willing to make a statement and answer any questions at this time. I do not want an attorney present at this time.

This is eastern michigan. Reporter holtzclaw, nicknamed the claw by teammates, was a football star in high school and an allamerican at eastern michigan university.

Reporter holtzclaw is little more than a rookie, just three years on the job, but already getting a reputation as an aggressive officer. A pair of brass knuckles in his patrol car. A local newspaper says he enjoys chasing down the bad guys as much as opposing running backs on the football field. His dad, eric holtzclaw, is a Police Officer, too, in the familys hometown of enid, oklahoma. I would say he was a Proactive Police officer. He liked to get in the mix. He wanted to catch the bad guys. He was very proud of that. He wanted to make a difference. Ive never been in trouble like this before. Ive never got accused of anything like this. Reporter but holtzclaw is a cop in a tight spot. We told you that there was a traffic stop right. That somebody made some allegations against an officer. Right. Reporter its 2 00 that morning, offduty, driving home in his police car, which many officers do in Oklahoma City. Holtzclaw made a traffic stop. Do you make traffic stops normally after work . I dont, but in that case i saw her swerve and what not. Reporter holtzclaw describes a routine stop. No ticket, just a warning about her expired drivers license. Im like, okay, im im just off work. Im tired. Get your license taken care of. And i cut her loose after that. Then where did you go . I went straight home. Reporter he admits he never bothered to call it in, and in another violation of procedure, had shut down the communications and gps tracking system in his patrol car, something he says he always did after work. So, did you run her on your mdt . No, i didnt. All my all my stuff as far as that, because i didnt call it in and say i was on a traffic stop. My computer was off and everything as well. Reporter but that female driver is telling police a very different story. She says the officer made her expose herself and sexually assaulted her right there in the back of his patrol car by the side of the road. Well, was there anything, an accidental touch, anything . If she thought it when i pat searched her. But i didnt. It was nothing as far as, i felt like i didnt do anything as far as sexual or anything like that.

Daniel being honest, straightforward, he had nothing to hide. Reporter detective davis disagrees. I just thought he was very robotic. Reporter he didnt express any shock.

Reporter in the heart of Tornado Alley in 2014, oklahoma has an easy year, less than 20 twisters. But in Oklahoma City, the Police Department is getting slammed with a manmade disaster. Oklahoma city Police Confirm they are investigating this claim. Reporter the force rocked by allegations against one of its own. Officer Daniel Holtzclaw is preying on those he is sworn to serve and protect. But now hes the one being pursued by sex crimes detective kim davis. And it is personal. For someone to use the badge and the gun to just do the most demeaning thing to a human being, its infuriating. It was my main focus. I i was going to put him in prison. Reporter the alleged victim, Oklahoma City native Jannie Ligons. She runs a daycare center, is f a grandmother of 12. I looked at my Rearview Mirror and i noticed those lights and it was a police car. Reporter she recalls the night she was pulled over along a section of 50th street. The officer told her she was driving erratically. I opened the door, he came to my car and he said, i stopped you because i saw you were swerving. Reporter he starts questioning her about a cup of koolaid seen in this police photo, and whether shes been drinking. She says she had not. But when the cop starts searching her, ligons says the traffic stop gets weird, and scary. She says he orders her to expose herself. And im like, what . You want me to take my pants down . Then he was like, yes. I said, oh, no sir. I said, youre not supposed to do that, sir. Reporter ligons says holtzclaw then forced her to commit a sex act on him as he stood by the open rear door of his police car. She was scared to death she was going to die. She didnt look at his face. She didnt look at his nametag. She said all she could stare at was his gun. Reporter in his police interview, holtzclaw acknowledges ligons was afraid of him. Did she ever ask you if you were going to shoot her . She did. She was talking about pistol all the time and talking about guns and whatnot. And im like, calm down. Im not. Im not going to shoot you or anything like that. Did she think you were going to shoot her . Maybe. Its disgusting, and this is my mother, who is a grandmother. Reporter ligons daughter, latoya riffa, sat by her mothers side during our interview. And he assumed that he could do this because theres no way shes going to report him, theres no way nobodys going to believe her. Reporter and did he say anything . He just backed up and he zipped his pants up and he moved back and i just got out of his police car and walked towards my car, thinking he was going to shoot me in the back. He let me live to tell the story. Big, big mistake. Reporter two hours later, encouraged by her family, ligons reports the assault to the police. If i could have went and found him myself, i would have gladly done so. Reporter do you want to take a moment . Are you okay . No, im fine. Reporter did you believe her . Yes, i did. There was no motive for her to make this up. Reporter detectives scour holtzclaws car for evidence, but find nothing more than fast food wrappers, muscle supplements and a Justin Timberlake cd. But when they examine holtzclaws uniform, hoping to find Jannie Ligons dna, they get a shock. They find dna all right, but its not hers, and its not from holtzclaws girlfriend either. There was unknown dna, female dna on the inside of his pants. Reporter detectives now deduce two things, the unknown dna may be another victim, and holtzclaw, a serial predator. The hunt begins for a match to the mystery dna. We werent going to stop until we found it. Juries today want dna because everybody watches csi. Reporter everybody wants the dna moment. Right. Reporter they begin checking the records of holtzclaws encounters with other women on his beat. I think we handsearched six paper boxes full of those, trying to find everybody he ran. Reporter so, thats, like, thousands of names, is my assumption. Oh, thousands. We just made a list of black females that he stopped and ran and started going door to door. Reporter behind those closed doors, and as the investigation widens, just what they feared, they find more women who say they too were attacked by a cop. And when the story leaks an officer has been placed on administrative leave. Reporter still more women come forward. Take the case of 22yearold shardayreon hill, who was handcuffed to this hospital bed high on drugs after an arrest when she says she was sexually assaulted. I didnt know what to think. I was scared, because i was just like, this is a Police Officer. I didnt know what to do, and then im handcuffed to the bed, so, im just like reporter youre powerless. Yes. Im in his custody. I dont know what he might do next, so, i just didnt even say nothing. Reporter and then theres carla raines, a 45yearold mother of two, who says she was forced to expose herself by an officer supposedly checking for drugs or weapons. So, it got to the point where i raised up my shirt. Okay, can i go now . Can you let me go . Reporter why didnt you report it . I didnt think that anything would happen. Reporter and then the police track down this woman. 39yearold sherry ellis. She tells a now familiar story. She was walking down highland drive when she was stopped by a cop in a squad car. And thats when he started doing things that he shouldnt be doing. Reporter what kind of things did he do . He was when he searched me, he searched under my clothes. He patted me down up under my clothes. Reporter ellis says the officer ran her name and found she had an arrest warrant and multiple unpaid fines. Hes like, well, okay, what do you think we need to do about this, miss ellis . And i said, i dont know, are you going to take me to jail . And i was looking down, because i was saying in the back of my mind, oh, my god, im going to jail, you know . And when i looked up reporter when she looked up, she says the officer forced himself on her, but her ordeal would not end there. Afterwards, she says he drove her to this abandoned schoolyard. He drove me to he drove me to a school. And outside of the school in the back and he opened the door and told me to get out and pull my pants down. And reporter and allegedly assaulted her again. When it was over, he said i was free to go. Reporter and now, police are connecting all those cases. The women, africanamerican and mostly middleaged, to that young, allamerican cop, Daniel Holtzclaw. An officer allegedly leading a double life on the night shift. Two months after his interrogation, he is arrested in the parking lot outside his gym. A Police Officer arrested officer Daniel Holtzclaw is in custody tonight, with several women coming forward claiming to be his victims. Reporter they have holtzclaw. They also have a growing list of accusers. But theres a problem. Not one of the women is a match to that critical clue, the mystery female dna found on the uniform. We kept going and kept searching, because we had to find a match. Reporter when we come back, Something Else thats not adding up. Is it possible police are chasing the wrong man . Your description doesnt match Daniel Holtzclaw. Stay with us. Hi, frank. I take movantik for oic, opioidinduced constipation.
