Andrade told investigators that he met Zapata through MocoSpace, a social network designed primarily for cell phone users, according to an arrest affidavit released by Greeley police. The two met July 15 and spent the day together.

Andrade told investigators that Zapata performed oral sex on him but wouldn't let him touch her, according to the affidavit.

He said he also spent the night at Zapata's apartment, but in separate beds. The next day, Zapata left Andrade alone in her apartment, and Andrade noticed several photographs that led him to question Zapata's gender.
