A 29-year-old Franklin man is being held in the Waukesha County Jail on charges of first-degree intentional homicide. Investigators say Sunkeun Kim beat his 24-year-old wife to death in her Brookfield condominium last Sunday. Madeline Kim had also been strangled. Investigators say she had filed for divorce last month following some domestic violence incidents. Her estranged husband was wearing a G-P-S tracking device which tied him to the murder scene.
