A $4,000 reward is being offered for information on who killed two dogs in north Fort Worth by giving them anti-freeze.
The two boxers, Nala and Bruno, died on Aug. 23. Police say a neighbor who had posted threats on Facebook is not a suspect.
Danielle Shelton said she took them to an animal hospital after they suddenly became sick, and the veterinarian determined they had both ingested anti-freeze.
Shelton, who owned Nala and was boarding Bruno, said she feels a wide range of emotions.
"Mad, sad, tears -- you know, everything; they were my babies," she said. "They were my kids."
Shelton said she has had an ongoing dispute with a neighbor who had posted threats against another neighbor's dogs in November.
According to a Fort Worth police report, the Facebook message said:
Local
The latest news from around North Texas.
Everyone that knows me knows that I am a dog lover...but if my neighbor (not you *******) does not shut their (expletive) dog up so I can get a nap I am going to accidently spill some antifreeze over their fence!!!!!!
In February, the same person also posted online threats against neighborhood children, the police report said.
One day (probably soon) on the news there will be a story titled "Children slaughtered in the streets" ... The murderer you ask....me!!! (insert evil laughter here) If these children do not calm the hell down I will kill them, and their parents for not raising them properly. I should not be able to hear thse (expletive) kids. And get off my (expletive) lawn and play in your own yard and get out of the street or I will mow your asses down!!"
A man who answering the door at the house where Shelton said the message-writer lived denied trying to harm the dogs. He said he had given a statement to police and took a lie detector test but declined further comment.
NBC 5 is not identifying the neighbor or his wife because they have not been arrested and police said they are not considered suspects.
Police spokeswoman Officer Sharron Neal said the investigation continues.
"As of today, the detective has no suspects," she wrote in an email.
"The detective is pursuing any and all active leads to learn who is responsible for this offense and will explore this further with a polygraph examination," she said.
She said the veterinarian was cooperating with the investigation to determine how much anti-freeze the dogs would have ingested to make them so sick.
