Task: Question Answering
Input (English): Passage: 15-year-old Genevieve Gage and her best friend, Tiana Moore, are typical high school students in Helverton, Colorado. The pair spend their idle time listening to music and going online, and Genevieve is a regular visitor to online chat rooms. As the pair are hanging out one night, Genevieve begins chatting with an online friend who goes by the alias of Captain Howdy. He invites the pair to a party at his house, and although Tiana is reluctant to go to a strangers house, Genevieve insists that times have changed and that she is being overly cautious.
When neither returns home by the next morning, Genevieve's mother, Toni, alerts her husband, local Detective Mike Gage. With the assistance of a younger Detective named Steve Christianson, Gage begins searching for Genevieve and Tiana. The case takes an unexpected turn when Tiana's car is pulled out of a lake with Tiana's tortured body inside and no sign of Genevieve.
Detective Christianson discovers a large gauge piece of body jewelry next to Tiana's corpse that is identified as a "septum spike" by the heavily tattooed tow-truck driver on the scene. He proceeds to explain the modern primitive subculture to the detectives, and asserts that the owner of the spike is a member of the community. He also gives them the location of a downtown nightclub, Xibalba, where the modified community hangs out.  They investigate the club, but find no promising suspects. Unbeknownst to the Detectives is that Captain Howdy is in attendance at the club, participating in a body suspension ritual in a back room. 
Question: What are the full names of the people who spend their idle time listening to music and going online?
Output (English): Tiana Moore.
