text: (CNN) -- A Florida corrections officer assisting in a manhunt died Wednesday in an exchange of gunfire with a murder suspect, who also died, authorities said. 
  
  Col. Greg Malloy, 44, was mortally wounded, the Florida Department of Corrections said in a statement. 
  
  Malloy was working as part of the Holmes Correctional Institution's K-9 tracking team, which was assisting the Holmes County Sheriff's Office in the search for Wade Williams. 
  
  Williams, wanted in the double homicide of his parents, was also killed during the exchange, according to the statement. The incident occurred about 13 miles from Bonifay in the Florida Panhandle. 
  
  "Words can never express our emotions when an officer falls in the line of duty," said Department of Corrections Secretary Walt McNeil. "Tragedies such as today's underscore the dangers inherent in our profession, both inside and outside the prison walls. We extend our condolences to Greg's family and his co-workers." 
  
  Malloy began his career with the Department of Corrections in 1988. 
  
  The Florida Department of Law Enforcement is conducting the shooting investigation. The Holmes County sheriff had not yet responded to a message left by CNN Wednesday afternoon.
