When Waukesha police officers responded to a 9-1-1 call Saturday night, they say they found a woman lying in the yard with a knife in her back. Her name hasn’t been released. She was taken to Waukesha Memorial Hospital suffering a wound which isn’t thought to be life-threatening. She’s in stable but serious condition. Officers say the suspect was arrested at the scene and is cooperating with their investigation. His name hasn’t been released either. Three children inside the home at the time of the stabbing are witnesses. They are staying with other members of the family.
