​Christopher Ryan Wall, 32, of Plano, was sentenced to 20 years in prison for Aggravated Assault with a Deadly Weapon, announced Collin County District Attorney Greg Willis.

On Feb. 6, 2015, Plano Police officers responded to multiple 911 calls reporting a crash at the intersection of Independence Parkway and Parkhaven Drive. Witnesses reported that Wall's black BMW was travelling at a high rate of speed while southbound on Independence when it struck the left front driver's side of a red Mazda turning left from Parkhaven.

The driver of the red Mazda, Rita Deysarkar, was found unresponsive and in critical condition. She was rushed to Plano Medical Center and underwent emergency surgery for internal injuries. She remained in a coma for over a month. Wall sustained only minor injuries and was released to police custody from the hospital.

Plano Police Officer Morgan Helmberger interviewed Wall, who showed signs of intoxication and admitted coming from a local bar. Officer Helmberger secured a search warrant for Wall's blood, which showed an alcohol concentration of .110 nearly four hours after the accident. Officer Steven Van Note and Officer Frank Benjamin, both experts in crash reconstruction, determined that Wall's vehicle was travelling 114 mph at the time of impact. The posted speed limit is 40 mph. Both officers determined that based on Wall's speed, the terrain, and lack of visibility, Ms. Deysarkar could not have seen Wall's vehicle in time to prevent the accident. She continues to suffer from her injuries.

Wall pleaded guilty to Aggravated Assault with a Deadly Weapon before Judge Benjamin Smith, who after hearing the evidence, sentenced Wall to 20 years in prison.

The case was prosecuted by Assistant District Attorneys Ryan King and Lisa King. They were aided by District Attorney Investigator Kenny Newton.
