A former Charleston County sheriff's deputy was accused of mooning people while drinking on Folly Beach weeks before separate allegations of excessive force surfaced, state records show.

Christopher Lanoue, 24, pulled down his pants and exposed his buttocks to the public June 6, according to documents the Sheriff's Office filed with the state about his termination. The incident, reportedly witnessed by two officers and a citizen, occurred around the same time a Folly Beach public safety officer confronted Lanoue and a friend about drinking beer in public.

Several hours later, supervisors went to Lanoue's house where he admitted to driving a personal vehicle home from Folly Beach while intoxicated. On the day of the off-duty incidents, a supervisor had granted him sick leave.

The Sheriff's Office terminated the deputy in late June.

"Officer Lanoue was under investigation for several departmental infractions," spokesman Maj. John Clark said. "The Sheriff's Office takes every infraction seriously and as part of our Early Warning System" — the department's way of monitoring employee behavior — "we look at the behavior of all Sheriff's Office employees."

Reached by phone Wednesday, Lanoue said he would rather not comment.

A separation form the Sheriff's Office filed with the S.C. Criminal Justice Academy describes the incidents on Folly Beach. The form gives several reasons for Lanoue's termination. They include giving false statements to supervisors and violating the agency's rules on using alcohol while off duty, which prohibits employees from drinking to the point of obnoxious or offensive behavior.

The Post and Courier obtained a copy of the form through the state's Freedom of Information Act.

The form also accuses Lanoue of using excessive force during two arrests on June 21.

In one instance, he delivered several knee strikes to the head and face of a mentally ill man while deputies were performing a welfare check at the man's house, the Sheriff's Office claimed. A supervisor had to make Lanoue stop.

Police reports describe a standoff during which the man appeared to be using his 10-year-old daughter to shield himself from deputies.

On the same day, video after a high-speed chase through West Ashley showed Lanoue kicking the handcuffed driver with- out provocation, the form states.

The State Law Enforcement Division arrested him Aug. 14 on two counts of misconduct in office. Lanoue left the jail the same day on two $10,000 personal recognizance bonds.
