Ebro - Washington county sheriff's deputies arrested one man tonight in connection with the deaths of 20-greyhound racing dogs at the Ebro Greyhound Park. But he's not yet charged with the animals' deaths.

State inspectors discovered 20 of the dogs inside one kennel at the Ebro facility. They belonged to a man named Ronny Williams. Ebro officials say they contracted with Williams to race greyhounds during the season, which ended about a month ago.

Under the agreement, Williams and the other owners at the park were supposed to find adoptive homes for their dogs or move them to another track still running races. They say Williams had yet to make any arrangements for any of his animals.

A representative from the local chapter of a national greyhound adoption program says she became suspicious of the condition of Williams' dogs, and called a state inspector. The state inspector found 20 of Williams' dog were dead, and 5 still alive.

Ebro officials made it clear Friday night that under their agreement the dog owners are solely responsible for the health and safety of their animals. At this point, authorities are trying to determine what killed the animals. It's possible they may have gotten some bad food or contracted some type of disease. But witnesses on the scene told us Friday night it appeared they'd been starved to death.

Ebro owners say they are devastated by the situation and want to get to the bottom of it as soon as possible.

Williams, the owner of the dogs involved, was arrested Friday night for driving with a suspended license. But he could face far more serious charges if authorities determine he was responsible for the deaths of the 20-dogs.
