Police said they discovered recorded threatening thoughts from Giles on his mobile phone, in which he said he wanted Free to die without any children. The couple, the Albuquerque Journal reports, hid in a closet in their home and called 911.
Police say an official ruling into how Giles died is still under review.
The suspect was named Christopher Giles of Albuquerque, New Mexico.
Christopher Eric Giles, 24, drove 11 hours from New Mexico to Texas before breaking into the video personality's home on January 26, FOX7 Austin reported.
A YouTube couple's home was broken into by an armed man who was obsessed with the internet stars. Austin authorities indicated that "it was apparent that Giles' sole intent was to cause harm to someone who resides there".
Turney and Free said they hid in the master closet until police arrived.
On Monday, the YouTubers expressed gratitude to their fans for their support and the Austin Police Department for their fast response to the emergency. He ran into police officers in the driveway, where he was ultimately shot dead.
It's Bad, It's Not Going To Be OK
Though Celebrity Big Brother just kicked off, the 13-episode season hosted by Julie Chen is set to wrap later this month. On the one hand, Omarosa is known for being dramatic (that whole unauthorized wedding photos in the White House thing).
It was reported that Giles had "developed a fondness" for Ms Turney, but disliked her boyfriend Mr Free. It seems like he envied Free's aspirational lifestyle and his romantic relationship with Turney.
Christopher Giles, who police described as "single, lonely and disturbed", had made the 11-hour drive from Albuquerque, according to documents filed in the 2nd Judicial District Court. The search revealed Giles "was an avid player of video games and was known for watching YouTube videos".
Giles reportedly fired gunshots inside and outside of the house, causing police to return fire.
"Thank y'all so, so much for each and every kind message today and a special thank you to the @Austin_Police for their quick response that night and their ongoing support during this hard time".
Free seems to have been the main target of Giles's ire, with more than a thousand notes related to him logged on the gunman's phone. "It's been a rough time for Meg and myself the last few weeks but we are doing OK".
