Mother, 25, facing DUI charges posted an Instagram video showing off her sports car just moments before she killed herself and a passenger in a high-speed crash

A 25-year-old woman who died in a multi-vehicle collision in Maryland had posted a video of herself speeding in her sports car just moments before the fatal crash.

Stephanie Angelica Vasquez, a 25-year-old from Kensington, had been driving the 2020 Toyota Supra that crashed into a Honda Accord in Gaithersburg late on Wednesday night.

Just moments before the crash, she posted several videos of herself on Instagram posing in the yellow vehicle and captioning it 'Imma kill it on the high way'.The person sitting in the passenger seat of the Supra, 35-year-old Jonathan Chakras, was also pronounced dead at the scene.

Detectives from the Montgomery County Department of Police said in a Thursday release that officers responded to the scene at around 6.37pm upon receiving report of a serious collision.

Vasquez had been traveling along Muddy Branch Road when she collided with the Accord as it tried to turn left onto eastbound West Deer Park Road.

Authorities believe that Vasquez had been speeding, which contributed to the collision. Three unoccupied parked vehicles were also damaged in the collision.

The driver of the Accord, identified as 40-year-old Heriberto Santos Gonzalez, was transported to a local hospital with serious injuries.

Two other men, who were not identified, were also transported to a local hospital with serious injuries.

Police are still investigating the collision.

GoFundMes have been made for Vasquez and the victims.

The Montgomery County Police Department shared that Vasquez was stopped on August 2 at 1.20am when an unmarked police cruiser observed her driving recklessly in Silver Spring.

After failing a field sobriety test, police discovered that she had a handgun in her glove department.

The mother was charged with driving under the influence of alcohol, transporting a loaded handgun in a vehicle, and possession of a firearm by a prohibited person.

Vasquez was due in court on Friday for those charges, WJLA reports.
