A police report filed at the station indicated she may have been killed elsewhere and the body dumped at the scene.

Detectives believe Wanjiku, a former employee at the Co-operative Bank in Embu, was kidnapped after someone lured her with the promise of helping her boost her Stima Sacco shares.

She withdrew Ksh350,000 from her bank account at the Co-operative Bank Stima Plaza branch on the afternoon of February 12.
