The man accused of killing his former girlfriend has filed motions asking a judge to throw out evidence in the case.
Black is accused of killing Susan Loper, a fitness instructor, and dumping her body off of the Dallas North Tollway before fleeing the state. He goes to trial in August.
The judge on Friday denied Black's motions to suppress evidence collected in the case through several search warrants but has yet to rule on specific information taken from Black's computer and iPhone.
His defense attorneys said they believe the evidence -- much of it from Black's home -- was illegally obtained.
Authorities served a search warrant at Black's home the day after Loper disappeared. Black's attorneys argued that the search warrant was invalid because police did not have enough on Black at the time to consider him a suspect.
While in the home, investigators saw that Black's computer was on. They downloaded a file called "how to win someone back" and took other personal writings about relationships.
U.S. park rangers eventually caught up to and arrested Black in Arizona after he tried to jump into the Grand Canyon.
Police found a laptop, iPhone and two suicide notes in Arizona. Black's attorneys argued that the computer searches were not outlined in the warrants and that any evidence from them should be thrown out.
The judge acknowledge that he was troubled by the computer searches and ordered both sides to file extended briefs on them before June 15.
Prosecutors say they have still have plenty of physical evidence that directly connects Black and only him with Loper's slaying.
