"I told him to calm down while I attempted to put handcuffs on him," Walls wrote. "He continued to struggle and told me he had a bad arm. I again told him to calm down and that I would help him up. ... He kept saying I had no reason to treat him this way and that I was going to have a lawsuit on my hands."
Walls wrote that he then helped McComb up and put him in the back of his cruiser.
Karen McComb, Robert McComb's daughter, said Thursday the family had been advised by their lawyer not to make any more comments about the specifics of the incident.
Cedar Grove Mayor James Hudnall said that Walls would be fired. He is on administrative leave until Aug. 30.
"He's not going to be working here as of Aug. 30," Hudnall said. "It's in the best interest of the town. I'm not accusing him of right or wrong. That's not been determined. But I think it's in the best interest of the town that he not be employed there."
On Wednesday FBI Supervisory Special Agent Joe Ciccarelli confirmed that the FBI had started a civil rights investigation into the incident.
Walls went through three other West Virginia police departments and twice received training in Ohio before becoming a fully certified officer, according to information provided to the Gazette by the state Law Enforcement Training unit of the Division of Justice and Community Services.
He was sued for his actions as an officer in Chesapeake. William Pullen won a $36,000 settlement against the city after accusing Walls of beating him when Walls was an officer there in 2006.
Walls also had worked at South Central Regional Jail, Paul O'Dell said Wednesday. O'Dell is deputy director for the West Virginia Regional Jail and Correctional Facility Authority. Walls worked at the jail from March 1, 2007, through Sept. 19, 2007, when he resigned for personal reasons, O'Dell said.
