JACKSONVILLE, Fla. -- A Jacksonville woman said she's worried about the safety of her dogs after someone broke into her Oceanway home and brutally killed some of her pets.

Josephine Bowles said her animals weren't just killed, but that they were cut and plucked until they were dead.

One of the killings took place earlier this week on Bowles' birthday. She said that was when she returned home to find one of her dogs dead and placed at the foot of her bed.

She said she has no idea why anyone would want to hurt the dog.

The morbid placement of the dog's body wasn't all that Bowles said disturbs her; she was also mortified because the dog was mutilated.

According to police reports, the dog "had been murdered via multiple knife wounds, and the dog's ears had been removed from his body."

"It's brutal murder the way they did it. They choked him, and then stabbed him, and then cut his throat, cut his ears off -- just multiple kind of things," Bowles said.

She told Channel 4 that two days after her dog was killed, her bird's feathers were plucked after its throat was slit.

Bowles said she buried the dead pets.

"They're back there. They took pictures, except the other one. They were talking about they wanted to dig that one up and do forensic tests," Bowles said.

She said a second dog was killed in similar fashion weeks ago but she never reported that incident to police. Bowles said she has become worried about what the killings mean to her safety.

"Whoever they are, they need to be found and put somewhere," Bowles said.

She said she suspects she knows who is behind her pets' deaths, but she remains worried about her remaining four Chihuahuas and one pit bull.

Detectives continue to investigate the incidents.
