A domestic dispute turned into a mass killing in southern Wisconsin, leaving six people, shot to death. A 2-year-old girl survived the attack.
A prosecutor said late Sunday no one was in custody but that police were not looking for a suspect and no one else was in danger. Officials often use such language when the shooter is among the dead.
"What we have is a complicated death scene and we're investigating all the possibilities," said Kevin St. John, a spokesman with the state Justice Department, which is leading the investigation.
Walworth County District Attorney Phillip Koss said the shooting was part of a domestic dispute, but he would not elaborate until autopsies were completed and the crime scene was fully evaluated.
Officers, responding to a report of shots fired, stormed a duplex Saturday night with weapons drawn, kicking in the door, neighbor Richard Heideman said. He saw two paramedics go in behind them and come back out minutes later.
"That's when I knew everybody was dead," Heideman said.
The 2-year-old girl was found in a nearby van, seriously wounded. A male family member who escaped the shooting was helping investigators.
Authorities have not released the victims' names, but Kay Macara said her 19-year-old daughter, Vanessa Iverson, was among the dead.
With tears in her eyes, Macara said her daughter went to the apartment the previous night to visit friends.
Also in the house during the shooting were the twin infants, their parents, and the mother's sister and her husband, said Sarah Iverson, Iverson's sister-in-law.
The 2-year-old sister of the twins, Jasmine, was in serious condition at University of Wisconsin Hospital in Madison.
The father of the children, 22-year-old Ambrocio Analco, was one of the dead, said Marco Pastrana, Analco's cousin. He said the twin boys were 2 to 3 months old.
Pastrana said Analco no longer lived with the children's mother. Analco left Pastrana's house Saturday night to drop the kids off with her at the duplex, Pastrana said.
Delavan, home to about 8,000 people, lies in the farm fields and woods between Janesville and Milwaukee. The P.T. Barnum Circus, "The Greatest Show on Earth," was founded in Delavan in 1871, and statues of circus animals decorate the town square.
