(ABCNews)-- Surveillance video led to the arrest of a Texas man for allegedly poisoning his neighbor’s dogs.
Matthew Alpers had complained to the Williamson County Sheriff’s Office twice in October and later in December that he found his dogs convulsing in the backyard of his Round Rock home on several occasions and that he suspected his neighbor Gary Thomas Ewald of poisoning them, police said.
Officials said they advised Alpers to install a surveillance camera “if he suspected his dogs were being poisoned … [to] verify if indeed this was taking place.”
The surveillance camera allegedly captured Ewald, 58, dumping liquid on Alpers’ backyard early this month, according to an arrest warrant, and Alpers said the liquid poisoned his dogs.
Officials told ABCNews.com that Alpers, 39, had three dogs, “two dachshunds and one white shepherd.”
Ewald was subsequently arrested and charged Dec. 19 with cruelty and torture to non-livestock animals, according to the county Sheriff’s Office.
Officials said Alpers told them that the dogs had recovered from the alleged poisonings. An animal hospital did not detect any toxic elements but is running tests after the third alleged attempt, which took place earlier this month, according to the arrest warrant.
Police said Ewald told them that the barking bothered him, but that the liquid he allegedly dumped was not toxic. “He stated he cleaned his Bar-B-Q pit and … poured [the remains] over the fence onto his neighbor’s back yard,” according to the arrest warrant.
Ewald has been released on $7,500 felony bond, Capt. Fred Thomas told ABCNews.com. It’s unclear whether he has entered a plea.
Alpers declined to comment on his allegations. “I want to let the investigation take its course and will not be making any comments at this time,” he said.
ABCNews.com has been unable to reach Ewald and the Heart of Texas Veterinary Specialty Center, where the dogs were treated.
The surveillance video has been submitted as evidence at the Sheriff’s Office.
