A retired detective who led the investigation into Suzy Lamplugh’s disappearance believes her body may have been dumped in a west London canal.

It’s 40 years to the day since the estate agent left her office in Fulham to meet a client.

Jim Dickie claims police searched the wrong stretch of water.

A prime suspect was identified and has since died.

Lizzie Lamplugh is Suzy’s sister.
