US police have arrested a man in Milwaukee in connection to murder of nine women dating back to 1986.
A police spokesman said Walter Ellis (49) was arrested on Saturday.
Prosecutors said he faces two counts of first-degree intentional homicide and more charges are expected.
Police said Ellis's DNA was found on the bodies of nine women who were killed between 1986 and 2007. Investigators believe eight were prostitutes and one was a runaway. They ranged in age from 16 to 41.

Online court records show that Ellis pleaded no contest in 1998 to a reduced charge of second-degree reckless injury. He was sentenced to five years in prison.
