The shocking footage, obtained by KLAS, is being used by prosecutors as evidence against 18-year-old Aaron Guerrero and his 16-year-old girlfriend Sierra Halseth.
“Welcome to our YouTube channel… Day 3 after someone’s murder…” Guerrero said, with a smirk on his face, into the camera.
“Whoa! Don’t put that in front of the camera, ”Halseth laughs.
“It was worth it,” Guerrero adds before pecking his girlfriend on the forehead.
The apparent admission was filmed in April days after they allegedly killed Halseth’s father, Daniel Halseth, 45, and set his house on fire.
They then fled in father’s blue Nissan Altima, but were caught less than a week later in Salt Lake City.
The father was murdered after their parents told the teens that they could no longer be together, KLAS reported, citing police.
Sierra’s mother, Elizabeth Halseth, was once a GOP state senator who was elected at 27 as the youngest person in the Nevada Senate in 2010, the Las Vegas Review-Journal reported.
