BONITA SPRINGS, Fla. (WKRC) — A man has been arrested following a gruesome discovery of animal cruelty.

Police responded to a home on Thursday after a resident found a box containing two severed cat heads on their mailbox, according to the Lee County Sheriff's Office.

"Heinous violent acts, especially toward innocent animals, is beyond unacceptable and any offender will face severe consequences to the fullest extent of the law," said Sheriff Carmine Marceno.

The investigation identified Robert James Luther III as a suspect. Detectives used advanced technology, including License Plate Readers and the Real Time Intelligence Center, to place Luther III at the scene of the crime.

Luther III was later found fishing near the mailbox and, during questioning, invoked his rights. Search warrants, including a DNA warrant, were executed, revealing evidence consistent with the investigation. Disturbing cell phone videos were discovered, depicting the deceased cats and implicating Luther III.

Detectives established probable cause to arrest Luther III on charges of two counts of aggravated animal cruelty and two counts of aggravated stalking.

"The combined efforts of multiple units ensured this sick individual got locked behind bars before he could hurt anyone else," said Marceno.
