The Sheriff's Office today said Deputy Chad Biernacki faces disciplinary action but did not release details on his punishment. Those details are expected to be available later today.

"There will be a suspension; I’m just not sure how long," Walton County Sheriff's spokesman Maj. AJ Smith told the Daily News.

The Florida Highway Patrol conducted the accident investigation and did not press charges against Biernacki, though finding him at fault in the accident. Biernacki has remained on active duty since the incident occurred, awaiting the findings from the FHP investigation.

According to the report, Biernacki had driven a Ford pick-up onto the beach to issue notices to appear to a group of underage drinkers around 6 p.m. on May 28. After issuing the citations, Biernacki was turning his truck around when it struck Jessica Nystrom of Destin, who was sleeping on the beach.

Nystrom, 21, was taken to Sacred Heart of the Emerald Coast with serious injuries but released the next day. Witnesses say she had a tire mark on her right shoulder.
