YAKIMA, Wash. — An examination of human remains found in a freezer near Toppenish last week could not determine the sex of the body, Yakima County Coroner Jim Curtice said.

A forensic pathologist examined the remains late Tuesday afternoon, Curtice said in a news release.

"The Coroner’s office is hopeful that identification can be made with the use of dental records and/or DNA," he said. "The death is being investigated as a homicide and the cause of death is still under investigation."

Authorities were called to the 64000 block of U.S. Highway 97 around 4:20 p.m. July 4 after two homeless men found remains in a freezer in a field where garbage is frequently dumped, sheriff’s spokesman Casey Schilperoort has said.

The Yakima County sheriff’s office, Yakama Nation Tribal Police and the FBI are involved in the case, as the remains were found on the Yakama Nation reservation.
