Radcliffe Franklin Haughton's wife, who worked at the spa in suburban Milwaukee, was recently granted a four-year restraining order against her husband after he slit her tires in the spa parking lot. She has been confirmed to be one of those killed.

The shooting sparked a six-hour man hunt during which a local mall was locked down before police were able to confirm Haughton had turned the gun on himself and was among the dead in the spa, according to the Chicago Tribune.

The hospital which treated the patients was briefly locked down, as well. From ABC:

The four injured women ranged in age from 22 to 40 and were taken to Froedert Hospital with what were described as non-critical injuries.

The hospital was briefly placed on lock down and only patients with a police escort were being accepted. Employees wishing to enter had to show identification.

Sheriff deputies searched the hospital before lifting the lockdown, apparently worried that the gunman had followed the victims to the hospital.

Sunday's shooting comes just two-and-a-half months after a mass shooting at a Sikh temple in Wisconsin left seven dead. The massacre also came two weeks after the one-year-anniversary of the Seal Beach shooting in which an estranged husband opened fire in his wife's salon, killing seven.
