Someone has left out open boxes of rat poisoning in Las Palmas park with "kill all dogs" written on one and "all dogs must die" on another. Police said there are no leads.
"We did put both of the boxes into evidence. Our CSI investigators are looking at them. We don't have any leads at this time. We have posted signs at the entrance to the dog park because we want to make sure that anyone who brings a dog here is aware that somebody is doing something out here," said John Pilger of the City of Sunnyvale.
Police are asking for the public to notify them of any suspicious behavior at the park. There are no dogs that have eaten the rat poison.
