LAKELAND, Fla. (WFLA) – A woman arrested on suspicion of killing her husband told deputies she slipped or tripped while holding a kitchen knife and accidentally stabbed him to death, according to the Polk County Sheriff’s Office.

Rachel Fidanian, 38, of Lakeland was arrested for second-degree murder and booked into the Polk County Jail on Wednesday.

On June 25, Fidanian called 911 to report that she had accidentally stabbed her husband, 40-year-old Brian Fidanian. He was taken to the hospital where he later died. Results from an autopsy suggest four inches of the blade cut through Mr. Fidanian’s second rib bone and cut the pulmonary artery. His death is being ruled as a homicide.

Deputies said Fidanian gave inconsistent statements about the stabbing. During the 911 call, she told the dispatcher she was holding her dog while doing the dishes, then ran toward her husband, slipped and stabbed him. She later told the dispatcher she was slicing pizza before she stabbed him, adding that it was an accident and she did not want to go to jail.

Fidanian told investigators she was slicing pizza when her dog started whimpering. She saw the dog was covered in feces and ran outside to pick it up. Fidanian said the dog was urinating and defecating itself all over the floor and her husband walked toward her to help. She walked towards him as well, then tripped on an area rug, fell and stabbed him.

Fidanian also told deputies she was wearing a black and red flannel robe when the stabbing occurred, but investigators found no signs of feces or urine on the robe, according to the report.

Detectives ultimately determined none of her explanations were plausible after she was unable to pick up her dog to demonstrate how she was holding it when the incident occurred.

“The suspect made a lot of excuses, but none of them made sense. Our detectives did a thorough investigation. In the end, they determined this was an intentional act of domestic violence. Incidentally, her arrest occurred during Domestic Violence Awareness Month,” said Polk County Sheriff Grady Judd.
