Giles apparently had developed an obsession with Turney and had notes on his phone that included one that said, "I want Gavin Free to die alone, with no children", per the search warrant, which was filed last week with a New Mexico state court. Hearing glass breaking, the couple hid and called 911.
But part of that investigation includes assistance from homicide detectives with the Albuquerque Police Department who served a search warrant on Giles' Northwest Albuquerque apartment a couple of days after the shooting.
After Giles was confirmed to have died, police undertook a search of his home and belongings.
He drove 11 hours from his New Mexico home to Austin, to confront the couple.
Christopher Eric Giles allegedly broke into the YouTube stars' home in an attempt to murder the boyfriend, police said.
The pair, who combined have over 10.6 million YouTube followers, addressed the incident via Twitter on Tuesday thanking those who had left messages of support while offering special thanks to the Austin Police force for their efforts on January 26. A shot was sacked from inside the auto, and one police officer returned fire. And his phone was full of notes suggesting he had "developed a fondness" for the woman, Megan Turney, and a dislike of her boyfriend, Gavin Free.More news: Suffragette stories come out of the shadows 100 years on

The officers found Giles backing out of the driveway in his Lincoln sedan with a New Mexico license plate and ordered him to stop.
Police say security footage shows Giles searching the home for residents while holding a gun, the Albuquerque Journal reports.
Turney and Free amassed internet fame through their YouTube videos. The search revealed Giles "was an avid player of video games and was known for watching YouTube videos". "Hey everyone. I just wanted to say thanks for all the support and concern regarding the recent incident", he wrote.
"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".
Turney wrote: "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". "It's been a rough time for Meg and myself the last few weeks but we are doing ok".
