(FOX40.COM) — The San Joaquin County Sheriff’s Office said deputies recovered human remains Wednesday in a vehicle they pulled out of the California Delta near 8 Mile Road. 

Just before 5 p.m. on Wednesday, deputies and crews from area fire departments were removing vehicles from the Delta and discovered human remains inside of one.

Sheriff’s officials said the vehicles were most likely stolen vehicles that were abandoned in the water, but that further investigation is needed in order to determine how they got there.

Officials are working to identify the remains and notify their family members.
