Questions & Answers
How did you find out how much alcohol the driver had consumed before the crash?
Willy suffered severe injuries and was rushed to hospital. Normal procedure in crashes like this is for Police to request a blood test be taken from the driver at the earliest opportunity for analysis later. In this case, Willy ended up having a full blood transfusion upon arrival at hospital, making a blood test invalid.
However, immediately upon arrival at hospital, a blood test was taken for medical reasons and from this sample, a reading of ethanol present in his blood was obtained. This was then converted to a blood alcohol level. This revealed a reading of 115 milligrams of alcohol per 100 millilitres of blood. (The legal adult limit is 80 milligrams of alcohol per 100 millilitres of blood).
How were you able to ascertain how fast the car was going just prior to the crash?
As control of the car was lost and it went into a slide (or yaw) around the bend, tyre friction marks have been left on the road surface. Calculations completed using the information from the tyre friction marks on the road surface gave a minimum speed of 155 km/h as the car lost control.
This speed was confirmed by Jared a year later when he was interviewed and stated that they were traveling at 180 km/h down the straight before Willy "tapped the brakes" before he tried to drift the car around the corner.
How do you know the back seat passenger's weren't wearing their seatbelts?
An examination of the seatbelts will usually reveal if they were worn in a crash.
When a seatbelt is put under loading during a crash, the force being applied to the webbing creates friction at webbing contact points, like where the webbing threads through the buckle. Heat is produced by this friction and causes localised melting of the plastic buckle cover. The melted plastic will adhere to the seatbelt webbing, leaving transfer evidence showing that the belt was in use at the time of the crash.It is clear from an inspection of the rear seatbelts that the rear seat passengers were most likely not wearing their seatbelts, and as a result have been thrown from the vehicle during the final stages of the impact.
What condition was the car in just prior to the crash?
Willy's car was in reasonable general condition and had a current warrant of fitness. However, both rear tyres were bald of thread and illegal. Regardless of this fact, no amount of tyre thread would have stopped the car from sliding out of control while trying to corner at such a high speed.
