GREENVILLE — A Liberty man died last Friday morning from a head injury sustained nine days earlier in an incident on the construction site at the Seneca Water Treatment Plant.

Charles “Chuck” Austin Keeler, 54, was pronounced dead at 6:33 a.m. Friday in the neurotrauma intensive care unit of Greenville Memorial Hospital, according to Oconee County coroner Karl Addis, who listed the cause of death as “accidental.”

Keeler was initially listed in critical condition after he was injured when a scissor lift overturned at approximately 8:15 a.m. Nov. 19 at the construction site for the city of Seneca’s $10 million water plant upgrade off Northampton Road.

A Seneca Police Department report stated the man appeared to have “significant head trauma” when police arrived. Seneca fire and rescue workers also responded.

“The gentleman was on the scissor lift up in the ceiling working,” Seneca Police Maj. Jeremy Rothell told The Journal that day. “The scissor lift turned over — we don’t know how. He was thrown from the lift, and he’s got some type of head injury.”

Keeler was working for Bonitz, a Greenville firm serving as a subcontractor for Harper Corporation, the contractor for the water plant upgrade. He was working in a new building being built as part of the upgrade for Seneca Light and Water.
