New video shows teenage driver speeding just days before he’s involved in crash that kills 18-year-old

(CBS DETROIT) — Police have released new video showing a teenager behind the wheel, driving at nearly 140 miles per hour.

The video shared with CBS Detroit shows Kiernan Tague driving dangerously fast in the days leading up to the senseless crash. CBS News Detroit obtained the disturbing video, along with a detailed police report, after filing a FOIA request.

Investigators say the teen was driving more than 100 miles per hour on a residential street in Gross Pointe Farms when he lost control of his car last November.

The 18-year-old and his friend Flynn Mackrell were killed in the crash.

Tague’s mother told police her son was violent and she was afraid of him. The police report lists multiple calls about both violence and speeding.

As we first reported on Wednesday, police say the teen’s mother was monitoring his driving on the Life 360 ​​app. The victim’s family is also seeking charges against the mother, saying she knew there was danger and didn’t take the keys.
