This doesn't give any details w.r.t. location or police report numbers or anything. It is simply assertion by defense attorneys. For all we know it could have happened in another state somewhere by someone's ex-boyfriend.
Moreover, the defense is complaining about not being given the incidents - isn't it their job to go find the incidents so they can create reasonable doubt? They are given a list of witnesses and they can depose them. It sounds like they are whining about not having done their own duties thoroughly.
Who is it? Who was convicted? I would read about his crimes in the context of the Routier case if I knew who it was.
The key word(s) in that paragraph are intruder and unknown assailant. If this guy were dating all these women he wouldn't be unknown to them and the crimes all occurred in the Dallas area as all the victims were taken to Parkland for their rape exams. Sammie Luckus Cook Jr. His appeal is on-line as well as an article about Gary Faison in which some of Cook's crimes are mentioned.
I beg to differ that they are just "whining" for not doing their own due diligence. For starters the issue is Brantley's testimony. He stated he had reviewed police reports in the geographical area looking for similarities to the Routier crime and had found none. Either he lied about how diligent his research was or he lied about there being no similar crimes. Any defendant, including Darlie, has the right to have only truthful testimony given against them.
Secondly, we don't know what Darlie's defense team had access to prior to her trial. All of these rapes were unsolved at that time and anyone who wanted to view the police reports may have been required to get a court order (common practice in most states if it's an ongoing investigation). You can't request a court order if you don't know what police reports you want to view. I remember debating with a woman on another message board who claimed to live in Dallas at the time and was emphatic no rapists were trolling the area during that time. Clearly there were at least three (or four including one traveling rapist who claims he returned to the Dallas area on occasion to rape women) active serial rapists in the area at that time and it wasn't exactly public knowledge.
