The site reported that authorities may be using the profile as evidence for their investigation into the mass shooting during a showing of "The Dark Knight Rises" on Thursday night.
"Holmes" created the profile on AdultFriendFinder.com July 5 — and included a picture of himself with reddish, orange hair just as officials in Aurora said he looked when he was arrested Friday morning.
"Holmes" used the screen name classicjimbo, and included a cryptic message on the top of the profile which reads, "Will you visit me in prison?"
In the profile, he described himself as a straight man and said he was seeking a sexual relationship with "Women, Couples (man and woman), Groups or Couples (2 women)." He also noted that he's interested in "Erotic Chat or Email, Discreet Relationship, 1-on-1 sex or Group sex (3 or more!)," TMZ reported.
According to the website, "Holmes" last logged in to the site sometime in the past three days. "Holmes" posted two different photos of himself, including one shot in which he is posed in front of an image of a woman while wearing headphones, according to the report.
