"Benfield refused to drop the shotgun, instead raising it and pointing it at one of the deputies," she said. "In response, two deputies fired their service weapons, striking Benfield and stopping the attack."
Benfield was taken to Leesburg Regional Medical Center, where he died.
Investigators said Benfield was released from the Florida Department of Corrections on Monday after having served a 25-year sentence for his involvement in a Lake County homicide and robbery.
The deputies, who were uninjured, were placed on paid administrative leave, which is standard procedure for shootings involving law enforcement officers.
The Florida Department of Law Enforcement is investigating the shooting.
