A teenage girl and her sweetheart charged with eliminating her daddy in Las Vegas laughed about “murdering someone” in a psychopathic mobile phone video they recorded while still on the lam.

” Welcome back to our YouTube channel … Day 3 after killing somebody …,” Guerrero, with a smirk on his face, says into the electronic camera.

“It was worth it,” Guerrero adds prior to pecking his girlfriend on the forehead.

The apparent admission was shot in April days after they allegedly eliminated Halseths dad, Daniel Halseth, 45, and set fire to his home.

The dad was killed after the teens were told by their moms and dads they might no longer be together, KLAS reported, citing police.

Sierras mom, Elizabeth Halseth, was as soon as a GOP state senator who was chosen at 27 as the youngest person to the Nevada Senate in 2010, the Las Vegas Review-Journal has reported.

They then fled in the fathers blue Nissan Altima, but were caught less than a week later in Salt Lake City.

” Whoa! Do not put that on cam,” Halseth responds while laughing.

The stunning video, gotten by KLAS, is being utilized by district attorneys as proof versus Aaron Guerrero, 18, and his 16-year-old girlfriend Sierra Halseth.
