When they say he was caught with "DNA" evidence, it must have been an abrupt thing. It must have happened and then she fled to police., cause they were able to get his dna from the victim.
There have been cases where a woman hollers rape 1-2 weeks after the fact w/no DNA (which is sketchy itself, cause u never know if its the truth or a vindictive girl) and the law just goes by a girls word that she was assaulted, but with DNA, its kinda lock stock n barrel = meaning he just bought the farm with that one 4 tryna strong arm the pussy.
