New bodycam footage shows Mackenzie Shirilla's father lashing out at Ohio police after her arrest for killing two people, calling her a 'dumb 18-year-old' and demanding they not question her.

Mackenzie, nicknamed 'Hell on Wheels,' was arrested on November 4, 2022, months after crashing her car into a building and killing her boyfriend, Dominic Russo, 20, and their friend, Davion Flanagan, 18.

Her father, Steven Shirilla, arrived at the Strongsville Police Department less than an hour later and spent nearly three minutes arguing with officers, calling her arrest 'unbelievable.'

In newly released footage obtained by Fox News, Steven is heard telling officers: 'I need to speak with my daughter.'

'You guys aren't allowed to speak with her at all, that's from the lawyer. He does not want you guys speaking with her,' he added. 'It's unbelievable, I mean she's 18.'
