A newly released police interrogation video opens with a chilling confession from convicted Utah killer Mia Bailey just hours after she executed both her parents.

Mia allegedly murdered the parents inside their family home during a bitter dispute tied to gender transition surgery and severe mental illness.

'I don't regret it. I hate them,' Bailey calmly told investigators just after Gail and Joseph Bailey were found shot to death inside their Washington City home in 2024.

Nearly two years later, the new footage shows Bailey's disturbing confession as she can be seen smiling while speaking with police officers about the heinous crime.

The transgender killer freely admits she carried out the killings and callously says she 'would still do it' if given a second chance. 

She goes on to describe in a matter-of-fact manner shooting both parents at close range, and claims that her mother, Gail Bailey, had tried to 'sabotage' the transition process before the murders.

Bailey, who was born male but had legally changed her name and gender before the killings, pleaded guilty to aggravated murder and aggravated assault in the June 2024 massacre.

In December 2025, Bailey was sentenced to two consecutive prison terms of 25 years to life.

In the newly interrogation footage, Bailey appeared strikingly composed while discussing the murders, at times speaking in a detached and emotionless tone as detectives questioned the killer about the attack.

'My grandma is the most supportive in my family,' Bailey told investigators at one point.

Bailey also described speaking with an aunt before the killings and claimed to have been spiraling emotionally.

'It was spur of the moment,' Bailey said of the murders, according to the interview recording.

But Bailey quickly followed that explanation with a far more chilling declaration.

'I'd still do it. I don't regret it. I hate them,' Bailey said. 'That was the last straw. I've forgiven them for so many things. Screwing me up so much.'

Police then asked Bailey directly what weapon had been used.

'A gun,' she replied.

Investigators followed up by asking whether it was the same firearm Bailey still possessed when finally surrendering to officers after an hours-long manhunt.

'Yes,' Bailey answered.

'Were there any bullets left in that gun?' police asked.

'No,' Bailey said. 'Why do you think I was trying to escape from you guys for a day? Trying to get myself one round.'

Detectives then asked if Bailey intended to commit suicide.

'Yes,' Bailey replied, while gesturing with two fingers pointing inside her mouth.

The interrogation grew even more disturbing when investigators asked Bailey to describe the actual killings.

'I parked there and pointed the gun,' Bailey said. 'I told myself to throw away that part of me. Ran through the door and shot them.'

Bailey then described the moments prosecutors say ended the lives of both parents.

'My mom was in a chair closest to the couch,' Bailey said.

'My dad walked out and said, "What's going on?" I didn't say anything and shot him.'

Bailey admitted shooting Joseph Bailey twice.

Court records previously revealed that Gail Bailey was shot four times, while Joseph Bailey suffered two gunshot wounds to the head.

The violence did not stop there. Bailey also admitted confronting one of her brothers during the attack.

'I saw my brother and said, "You've ruined my life,"' Bailey told investigators, before adding the anger 'wasn't so much directed at him as my parents.'

According to prosecutors, Bailey's brother and his wife barricaded themselves inside a bedroom while Bailey fired through the door. The brother ultimately escaped and called for help.

Authorities later launched a widespread manhunt before Bailey was captured roughly 16 hours after the shootings.

Investigators said Bailey blamed worsening mental health struggles and family conflict surrounding gender transition surgery for the murders.

According to prior court filings, Bailey accused her mother, Gail, of attempting to 'sabotage' the transition process.

Defense attorney Ryan Stout told the court that Bailey had suffered from severe mental illness for years before the killings.

During sentencing proceedings in December 2025, Stout said Bailey had been diagnosed with ADHD, OCD, anxiety, depression, psychosis, possible bipolar disorder with psychosis and schizophrenia.

'The most recent time she committed herself [to the hospital], she was discharged three days later, and 10 days later she murdered her parents,' Stout told the court.

The sentencing hearing itself produced another startling revelation.

In a statement read aloud by Stout, Bailey said the killer had converted to Islam while incarcerated and claimed religious beliefs justified severe punishment.

'Because of my religious beliefs as a Muslim, it would be appropriate to take my life for atonement for what I did,' the statement said.

Bailey had also attempted to avoid attending the sentencing hearing altogether, arguing that hearing details of the murders again could trigger a mental breakdown.

But the emotional centerpiece of the hearing came from surviving family members who described a family shattered beyond repair.

Corey Bailey told the judge he believed prison was the only safe outcome.

'What's best for us and what's best for Mia is probably staying in prison for as long as possible,' he said.

'We've lost our parents, and we've lost a sibling in many ways as well. So either way, no matter what, we are losing as a family on this sentence.'

Another brother, Dustin Bailey, addressed Mia directly in court and acknowledged the obvious signs of mental collapse leading up to the murders.

'It was clear you were not safe or well,' Dustin said.

But he also defended their slain mother, rejecting any suggestion that Gail Bailey had abandoned her child.

'When Mia struggled, Gail's response was not frustration or withdrawal,' Dustin told the court. 'It was persistence.'

Dustin added that Gail Bailey had repeatedly tried to secure help and support for Mia throughout years of worsening instability.
