Wildlife officials recovered the bodies of the endangered animals on March 22 and 23 off Porter Mountain Road in the Apache Sitgreaves National Forest, about 200 miles northeast of Tucson. The U.S. Fish and Wildlife Service and its partners are offering up to $37,000 for information leading to an arrest in the case. In a statement issued Friday, service officials said they hope to hear from anyone who might have seen a vehicle that was stopped or driving slowly off Porter Mountain Road or who has any information that could be helpful in finding those responsible for the deaths.
