Man heard saying he is dying in empty field


2 off of 36 to start for a 952[1] at 5095 Stockton Boulevard and 6B. Callers advising it in the empty field near that 925 can hear a (name withheld) voice saying that he's dying. Nothing else seen or heard. A caller then disconnected and unable to call back to 9-1-1-only cell phone. No history with the phone number to 952 and 6B. Sam fixed a copy.
