His girlfriend told the deputy that Fletcher has a history of hurting animals when he gets upset and has previously killed his ex-girlfriend's animals, according to the report.
Investigators said Fletcher admitted to the incident and was arrested on charges of animal cruelty.
"Due to this suspect’s inability to control his temper, he inflicted significant pain and injury on a defenseless animal," said Bob Kealing, a Sheriff's Office spokesman. "As a result, he is facing serious felony charges."
Fletcher is being held at the John E. Polk Correctional Facility in lieu of $10,000 bail.
His court hearing is scheduled for 2 p.m. Wednesday.
