LAS VEGAS (KLAS) — A teenage girl and her boyfriend were sentenced Thursday morning to life with the possibility of parole after 22 years in prison for the murder of the girl’s father.

Sierra Halseth and Aaron Guerrero murdered 45-year-old Daniel Halseth in April 2021. The coroner’s autopsy report said he had suffered 70 stab wounds and was “burned from head to toe.”

Prior to the sentencing, the defendants and family members were given the opportunity to speak. Sierra Halseth claimed her father abused her. Her family members also spoke. Daniel Halseth’s sister called the crimes “unforgivable” and said she believed her niece and the boyfriend should get the death penalty, even though that wasn’t an option. Daniel Halseth’s mother said she is haunted by the description of his death.

“Medication and counseling does not stop the pain in my heart,” she said.

Guerrero apologized to the court.

During the sentencing, Clark County District Court Judge said she wished there was something she could do to stop the suffering.

The sentencing was part of a plea deal for Halseth and Guerrero who agreed to the deal to avoid the death penalty against Guerrero who was 18 when the crime was committed.

Halseth and Guerrero began dating in the summer of 2020 but stopped a few months later when their parents intervened after learning the two were planning to leave for Los Angeles so they could continue to see each other.

Daniel Halseth’s body was discovered on April 9, 2021, inside his home.

Four days later, Halseth, who was 16 at the time, and Guerrero, who was 18, were arrested in Utah.

Police found a video on Halseth’s phone of the two laughing and talking about her father’s killing.

“Welcome back to our YouTube channel day three after murdering somebody,” Guerrero said on video. Halseth responded, “Whoa, don’t put that on camera.”
