Cold case detectives search for remains of WA woman

Cold case detectives are sending cameras down hundreds of mineshafts in WA's Goldfields as they search for the remains of Jennie Kehlet.

9News was alongside police as they used the cameras to search the 300 mine shafts.

It's the new cold case team's eighth trip to the Goldfields this year.

Covering more than 2000 square kilometres, they're forced to think outside the box.

"We've made up a box with recording equipment that we're sending down into as many mine shafts as we can just to see what's at the bottom of the mineshafts to see if we can locate Jenny," Detective Sergeant Peter Sloan said.

In 2015, Ms Kehlet was prospecting with husband Ray Kehlet and an acquaintance.

Mr Kehlet's body was discovered deep down a mine shaft and his wife is still missing, presumed murdered.
