A suspected ‘serial killer’ is on the loose in northern California after six people have been shot dead over the past 18 months.
Police admit they have been left baffled as the gunman appears to be “on a mission” although his motive is unclear.
He has so far struck seven times, shooting dead six men and wounding one woman, in a killing spree in the Stockton and Oakland areas since April 2021, with five of the fatal attacks happening in the last three months.
