Adriana Biggs, the head of the District Attorney’s White Collar Crimes section, is no longer with the District Attorney's Office, District Attorney Susan Reed confirmed to KSAT 12 on Thursday afternoon.

Biggs' son, Truman Biggs, was arrested on a drunken driving charge in 2012. The case was later dismissed, despite a blood alcohol report for Truman Biggs listed at 0.15.

The special prosecutor assigned to the case, Defense Attorney Charles Bunk, denied any outside influence in his decision to seek a dismissal of the charges.

“I just happened to be in the courtroom,” Bunk told KSAT 12 on June 3. “I was not sought out or solicited.”

He denied getting any pressure to seek a dismissal.

“To this day, I’ve never spoken to anybody in the District Attorney’s office other than to receive the file,” Bunk said.

He said he made the decision to file a motion to have the case dismissed after viewing dash camera video recorded by the Terrell Hills Police Department and reviewing police reports.

Susan Reed has said she deliberately has not followed the case.

She also said she will not publicly comment on personnel matters other than to confirm that Adrianna Biggs is no longer with the office.
