How was Josh even arrested in the first place..

A crime happened on the UW Campus in Madison in October of last year and the victim gave the description of a young lad whom she believed did it. She gave a description of a plain red shirt, cacky pants or shorts and nike tennis shoes, no jewelry, 5"11 to 6'2 brown hair, unshaven young man in his early 20's. The girl did have a rape exam done and was asked questions. The detectves secured the area to look for evidence. The detectives went right to work to look for suspects with a red shirt, cacky pants and Nike tennis shoes. The detectives were able to secure a video of a young lad back paddleing (walking backwards in front of the girl) and the girl was seen in the video following him--walking straight towards him..now if I was the detective I would've scrutinized this video and asked myself several questions 1. this girl does not look scared, she is walking towards him..looks like she knows him. does not hestitate or stops to pull out her phone that she does have on her or even tries to get away to the 3 other exits that she could've taken to get away from this person. so right away I would say that she is not afraid of him..and maybe makes a decision to be with him...but we do not know anymore about what happened than what is on this video rignt now.. ok now let's try to find the person who did this crime..well we will look at the video's in all the bars that night around that time and look for young men wearing a red shirt and tennis shoes, now we will look at the overhead cam's on the streets..and see what we can find. well we find a young man with a red shirt that says (WISCONSIN BADGERS) on his shirt. we also see that he is wearing cacky pants and also tennis shoes..he isn't 5'11-6'2 but he is a close enough match..let's bring him in and question him. and then the detectives question him..
