BROOKFIELD, Wis. -

Authorities say all seven of the victims in Sunday's fatal spa shooting in suburban Milwaukee were women.

Brookfield Police Chief Dan Tushaus did not identify the victims by name during a news conference Sunday night.

Three women were shot and killed at the Azana Day Spa in Brookfield, but Tushaus did not provide their ages.

He said four women were taken to the hospital, ages 22, 30, 32 and 40. The hospital said one woman was in critical condition and another was satisfactory. It did not give conditions for the other two but one was expected to have surgery and the other was admitted but did not require surgery.

Police say the suspect, 45-year-old Radcliffe Franklin Haughton, was found dead of a self-inflicted gunshot wound.

Haughton's wife worked at the spa. It is not known if she was one of the victims.
