(Oxford, MS) Friday, The Mississippi Highway Patrol spent the day on Highway 278 trying to re-create last Saturday's deadly crash that killed a brother and sister.
Investigators hope a computer animation will help them determine how 21-year-old John Strickland, veered his truck over the median and slammed into a coupe, killing 30-year-old John Wheat and his sister, 24-year-old Sarah.
Police aren't sure what caused the Ole Miss student to veer into oncoming traffic, hitting two fellow students.
"The day of the crash, we received a warrant based on probable cause to draw blood of the driver," said Oxford Police Chief, Mike Martin.
Right now, police are waiting on those blood tests to see if Strickland was drunk or high at the time of the crash.
"The driver is not charged with anything at this time," said Martin.
It took several days for Oxford police to say who was to blame for the deadly wreck, until community online newspaper, Hotty Toddy, forced them to through the freedom of information act.
Martin said it's normal to hold the names of drivers in fatal wrecks during the investigation, "This could result in a court case. We want to make sure we do everything correctly and that we don't do anything that would result in any possible court actions."
Detectives won't know if the case will head to court until Strickland's blood tests come back in a couple of weeks.
