A Pulaski County grand jury has indicted a man who police say beat his wife so badly last year that she suffered a brain injury.
The investigation began Aug. 20, 2012, when Christopher Todd Smith, 44, of Burnside called the Pulaski County 911 Center and said he came home from work and found his wife, Tammy Mullins, unresponsive on the bedroom floor.
Officers were not called initially because Smith reported the injury as a medical emergency, according to a news release from the Pulaski County sheriff's office.
Mullins was taken by helicopter to University of Kentucky Chandler Hospital.
While treating her, medical workers noticed "unexplained bruising and injuries on her head and body," and detectives from the sheriff's office began investigating, according to the news release.
Mullins had a brain injury that the sheriff's office said "substantially affected her memory" and left her struggling to remember how she was hurt.
There was a history of domestic violence in the relationship, and the investigation led detectives to suspect that Smith had assaulted Mullins on Aug. 19, then went to work and came home to find her "unresponsive."
After a yearlong investigation that culminated in a grand jury indictment, officers arrested Smith on Monday night. He was charged with first-degree assault and was being held Tuesday in the Pulaski County Detention Center in lieu of $100,000 bond.
