Woman explains why she killed her ‘best friend’ after a man online offered her $9,000,000

Chilling footage shows a convicted murderer explaining why she killed her 'best friend'.

Last year, Denali Brehmer admitted to first-degree murder after killing her friend Cynthia Hoffman in June 2019 near Thunderbird Falls in Chugiak, Alaska.

As per the Alaska Department of Law, Brehmer made the guilty plea after stating a man on the internet promised her $9 million for photographs and videos of her committing murder.

Brehmer was in a relationship with Darin Schilmiller, who claimed he was a multimillionaire but was instead living in his grandparents’ basement in Indiana.

Authorities say the pair planned a series of crimes in exchange for cash, including the 'rape and murder of someone in Alaska'.

Alaska men Kayden McIntosh and Caleb Leyland were also sent down for second-degree murder after helping Brehmer murder her friend.

The group went on to trick their victim into coming to Thunderbird Falls, saying that they were going on a hiking trip before they shot her.

Hoffman's body was then dumped into the Eklutna River.

Earlier this year, Brehmer was sentenced to 99 years in prison for the murder of her friend.

The tragic story is the focus of Court TV’s Interview With a Killer newest episode, with Brehmer herself explaining why she murdered Hoffman.

She told host David Scott: "Initially, when we all came up with it, I agreed and said yeah because I was mad at her and she was mad at me and I was just over her s***."

Brehmer spoke about an argument she had with Hoffman about another man named Zack.

"I wanted to make amends, I did want to make amends but she needed payback for what she did with Zack," Brehmer continued.

The convicted killer went on to state the murder is 'on me', though wasn't clear on whether she wanted to actually murder her friend or just scare her.

She said she was 'somewhere inbetween' kidding and being serious when she set out to murder Hoffman.

She later added: "I wanted her to pay for what she did but I didn't want to kill her. I wanted to leave a lasting impression on her."

Former FBI agent Brad Garrett and TV host David Scott will be unpicking the case in the new episode of Interview with a Killer, which airs tonight at 8pm ET on Court TV.

They reveal Brehmer was 'no naive, unwitting victim of a bad online influence', with Scott adding in the show: "It’s not clear to me who was the predator and who was the prey in this case of catfishing."
