Prosecutors push for trial in Colorado case

Prosecutors also used Holmes' dating website profiles to try to prove he knew the consequences of his actions. On two social networking websites — Match.com and FriendFinder.com — Holmes asked: "Will you visit me in prison?"

The Match profile was created in April; the FriendFinder account was opened on July 5. Holmes last accessed the sites two days before the July 20 shooting at a midnight showing of "The Dark Knight Rises," detective Tom Welton testified.

As prosecutors lay out their case, Holmes' lawyers have been asking questions throughout the hearing that suggest a mental health defense.

Attorney Tamara Brady asked Steven Beggs, an ATF agent who testified, whether there was anything to prevent "a severely mentally ill person" from purchasing things like chemicals, ammunition and handcuffs.

He replied no.

Defense attorney Daniel King asked Appel if Holmes was tested for drugs or other substances.

"I saw no indication that he was under the influence of anything," Appel said.
