SAN DIEGO, Calif. (CBS 8) -- For the first time, we are hearing audio of the 911 call that led to the discovery of four graves and the remains of the McStay family near Victorville, Calif.
The call was made on November 11 at 9:58 a.m. by an off-road, motorcycle rider in the high desert, according to authorities.
Only the first portion of the 911 call was released under a public records request to CBS News 8 by California Highway Patrol dispatchers.
It ends with the caller being transferred to the San Bernardino Sheriff's Department, which declined to release the remainder of the call.
The CHP recording provided to CBS News 8 ran just over a minute and a half in length:

CHP dispatcher: What are the closest cross streets?

CHP dispatcher: Okay, that could be anywhere, sir. What are the two closest cross streets?
Caller: There's no paved roads around here.
CHP dispatcher: Okay, there has to be a cross street. You can't just say the 15. The 15 goes from San Diego to Utah.

No suspects have been identified in the McStay murders. The Fallbrook family of four mysteriously went missing in February 2010.
Following the discovery of remains, detectives announced the bodies had been found "largely intact" but no cause of death was announced.
Over the weekend, a memorial paddle out was held next to the San Clemente pier in honor of Joseph McStay, 40, his wife Summer, 43, and their two sons, Gianni, 4, and Joey, Jr., 3.
