Police in the US state of Arizona say a man arrested last month is responsible for a series of deadly shootings in Phoenix last year.
Aaron Saucedo, 23, had already been charged with murder in connection with a killing in August 2015, police say.
Now he has been linked to the deaths of eight other people, between January and July 2016.
Police say they have not identified a motive but believe he acted alone. His lawyer has not commented.
