Several factors appeared to play a part in why a warrant was not sought for evidence regarding Walton’s blood-alcohol level at the time.
A DPS spokesman said no prior DWI convictions showed up when her criminal history was checked the night of her arrest and Walton was charged with a first offense DWI, a class B misdemeanor.
However, the Democrat confirmed that Walton does have a previous conviction for DWI in Arkansas in 1998.
If there is a refusal to provide a breath or blood sample, troopers in Parker County typically seek a warrant for a blood draw in cases of a suspected felony offense or a death investigation, according to DPS Senior Trooper Gary Rozzell.
Though law enforcement officers in the Metroplex may seek a blood draw warrant while investigating a suspected first or second DWI offense (both misdemeanors), judge availability and cost limit that in Parker County, according to Rozzell.
Walton’s driving record has been in the news several times.
According to news accounts, Walton was also involved in a 1989 wreck in Arkansas that resulted in the death of a 50-year-old woman though no charges were reportedly filed.
