Tausha Dion Borland, 38, is accused of two counts of first-degree manslaughter plus two other counts — leaving the scene of a fatal accident and DUI involving a personal injury.

Borland is accused of fatally injuring Christa Voss, 33, of Owasso and Matthew Edmonds, 34, of Tulsa. Authorities said Voss died at the scene, while Edmonds died later at a Tulsa hospital.

The third cyclist, John Moore, 40, of Broken Arrow, was treated at a hospital and released, the Oklahoma Highway Patrol said.

Borland was released from the Tulsa Jail on June 10 upon posting bond on $100,000 bail.

Assistant District Attorney Steve Kunzweiler applied Wednesday to increase her bail, asserting that the current amount is “insufficient to protect the public.”

He requests that Borland’s bail be increased to $500,000 and that conditions be imposed on her if she is released. Those proposed conditions include an ankle monitor, a curfew, no driving and no consumption of alcohol or illegal substances.

A hearing on that matter is set for Friday.

The three bicyclists were hit from behind on the shoulder of Oklahoma 51 near 165th West Avenue, a few miles west of Sand Springs, on the afternoon of June 9, according to reports.

State troopers said Borland’s sport utility vehicle swerved out of her lane and onto the shoulder,

Troopers said Borland did not stop immediately but continued driving for another quarter of a mile.

According to Kunzweiler’s application for a higher bond, reports indicate that the windshield of Borland’s vehicle “had two separate and distinct impact indents upon it” from two of the three victims.

An eyewitness saw Borland’s vehicle strike the victims and described Borland as “stumbling out of her vehicle as she asked him what happened,” according to Kunzweiler’s document.

After the witness told the defendant that she had hit three bicyclists, Borland said that “she didn’t realize she hit anything” and pleaded with the witness not to call the police, the prosecutor’s filing says.

According to the witness, the defendant said: “I have been drinking. I’m drunk and don’t want to go to jail,” Kunzweiler wrote.

Tulsa County court records show that Borland incurred a six-month suspended sentence and a misdemeanor conviction in 2007 in a case that originated as a DUI charge but which was amended to driving while impaired.

Word of Wednesday’s charges quickly spread throughout the city’s cycling community. Many riders are following the case and were awaiting the filing, said Adam Vanderburg, who owns Lee’s Bicycles and the Trek Bicycle Store.

“They’ve really got their ears open on this, and everyone is very interested in what the final outcome will be,” he said.

When contacted about the case Wednesday, a woman who answered the phone at Moore’s residence said Moore did not want to comment.

Although the crash still weighs on riders in the area, it drew attention to the friction between motorists and bicyclists, Vanderburg said. Drivers often see cyclists as second-class citizens who shouldn’t be on roadways, he said.

Bicyclists often vie for road space with aggressive drivers who speed past at dangerously close distances, Vanderburg said.

“Instead of seeing bicyclists as the normal traffic flow, they see it as an obstruction that they have to dodge. Oftentimes, that means putting somebody’s life at risk,” Vanderburg said.

But under Oklahoma traffic laws, cyclists have many of the same privileges as truck drivers and motorcyclists, said Malcolm McCollam, an attorney and bike enthusiast.

Bicyclists can ride on public streets and aren’t limited to bike lanes, and drivers are required to leave a 3-foot buffer when they pass, McCollam said.

Despite the legal protections, cyclists still contend with hostile drivers, he said. Some motorists are aware of the law but simply don’t follow it, he added.

“Anybody who has spent any time on a bicycle out on the roads has had somebody yell at them,” McCollam said. “They think somehow that you’re encroaching on their turf and that those roads are theirs.”
