Arizona Game and Fish officials are trying to catch someone who has been illegally poisoning wildlife in the Canada del Oro Wash.
Game and Fish is offering a reward of $500 for information leading to the arrest of the person.
Officials say two javelinas and an owl were found dead in the wash. Two dogs were also found poisoned in the wash. One is dead and the other is still sick.
"If you are using pesticides, you may only legally do so on your own property, and in a way that doesn’t put wildlife at risk,” said Regional Supervisor Raul Vega of Game and Fish in Tucson said in a statement. "While the apparent poisonings of the pets and wildlife may be inadvertent, we are investigating this as a possible criminal violation nonetheless."
Game and Fish recommends using humane, standard mouse traps, rather than poison, to trap pests such as packrats.
