According to Brunswick County Sheriff's Office (BCSO), Rivenbark was arrested around 1:45 a.m. while driving on US-17 in the Leland area. He was cited for failing to maintain lane control. A blood test revealed a blood alcohol level of 0.11, over the legal .08 limit.
According to the warrant for his arrest, both a BCSO deputy and a Leland Police Department officer were witnesses.
Rivenbark was released without a cash bond payment after a judge accepted a "written promise" to appear in court, according to BCSO. His next scheduled court date is June 27.
In an email, Rivenbark wrote, "[l]ate on the night of May 10 I received a call from my son, who was experiencing an adverse medical event. At the time I was on a trip with colleagues in Myrtle Beach. My son is a quadriplegic and his health and well-being are my top priority. Later that evening I made the decision to leave Myrtle Beach and come home to be with him and to help his mother. I did not think that I was impaired. In hindsight, it was not the right decision but it was the one I made based on the knowledge that he was in pain. I accept responsibility for my actions and I am truly sorry for this situation I have created."
