ARLINGTON -- An Arlington man is accused of reaching for his breathalyzer when his pickup truck crashed into the vehicle of an 18-year-old woman and killed her as she backed out of the driveway of a home in early November.

The Arlington Police Department arrested 31-year-old Blake Austin Cowan on Friday, Dec. 15, and charged him with manslaughter in the death of Alexis Butler.

According to an arrest affidavit obtained from the Arlington police, the fatal crash occurred on Nov. 10 at 6:20 p.m.

The affidavit states that Cowan was driving a 2014 Chevrolet Silverado in the 3700 block of Redstone Drive at nearly twice the posted speed limit as he was traveling eastbound. The posted speed limit on the street is 30 mph, and an investigation into the crash revealed that Cowan was accelerating at almost full speed up until a split second before the crash.

Butler, who was driving a 2016 Toyota Camry, appeared to have been reversing out a private driveway on Redstone Drive.

Police believe that Butler had been traveling westbound in the 3700 block of Redstone and had missed a turn, causing her to pull into the private driveway to turnaround. She was headed to a home in the 3400 block of Heatherbrook Drive that was about 500 feet away from where the crash occurred.
