Zina Haughton, wife of the alleged gunman, was one of the three victims in Sunday's shooting at a Wisconsin salon.
The Waukesha County medical examiner's office released the names Monday of those killed in suburban Milwaukee: Cary Robuck, 35; Maelyn Lind, 38; and Zina Haughton, 42, of Brown Deer.
Radcliffe Haughton was found dead after he killed the three people, police said.
Four days ago, Zina Haughton took out a restraining order against her husband.
A survivor tells CNN affiliate WTMJ-TV that Zina Haughton was a hero - and saved lives.
One person wounded in Sunday's shooting has been released from the hospital, a spokeswoman for Froedtert Hospital announced Monday.
The hospital didn't identify the patient who was among seven shot by Radcliffe Haughton at the Azana Salon and Spa in Brookfield.
Of the three patients remaining in the hospital, all are in satisfactory condition, including one person whose condition was upgraded Monday from critical.
