James Holmes, the man suspected of killing 12 and wounding dozens of others during a shooting spree at a screening of "The Dark Knight Rises" in Aurora, Colo., last month, reached out to "Pimp My Ride" star "Diggity" Dave Aragon in the weeks leading up to the massacre, the MTV personality told CBS's Los Angeles radio station KNX 1070.
According to Aragon, Holmes reached out to him about the trailer for Aragon's upcoming film "The Suffocator of Sins," described by Aragon as a "very sick and dark twist on the Batman movies."
Aragon told KNX 1070's Charles Feldman that a man identifying himself as "James Holmes" called him the month before the shootings, and peppered him with questions about the trailer and the upcoming film.
Holmes showed a particular interest in the violent aspects of the film -- which depicts Batman as a vengeance-prone vigilante who guns down bad guys, in stark contrast to the "Dark Knight" version of the superhero, who declines to pack heat.
“He would tell me what he really liked about the trailer. He kept pressing if I could give him more information on the story. He wanted to know how many people Batman kills,” Aragon told Feldman. “He wanted to know if it was selective killing. Does he make a list of people he wants to kill, or is it a mass body count?”
Holmes -- who said he watched the trailer more than 100 times, according to Aragon -- also expressed his disappointment with the fact that the Batman of "The Suffocator of Sins" did not use bigger guns.
Aragon added that Holmes "talked about the Joker" -- the Batman villain that Holmes reportedly identified himself as when he was apprehended by police following the shootings.
Earlier this week, Holmes was charged with 24 counts of murder and 116 counts of attempted murder in connection to the "Dark Knight" shootings. Police say that he began stockpiling the weapons and body armor that he allegedly used in the shootings in May and June.
