The body was discovered in a brushy, remote area near Sunol Saturday afternoon by a volunteer working with a search team organized by Le's family.
Alameda County investigators sealed off access to the crime scene. The area has been previously searched by Hayward police.
"Today, one of the search party members did discover remains," said Lt. Roger Keener with the Hayward Police Department. "Right now that's all we know. There is nothing that indicates gender with the remains. The body is decomposed."
Authorities say DNA tests will need to be conducted to positively identify the body. The Alameday County Crime Lab technicians are on the scene to collect evidence.
Ten days ago, police arrested Giselle Esteban in connection with Le's murder. Le disappeared from the Hayward Kaiser hospital where she was a student at the end of May.
