Six people have been found dead and a child badly injured after a shooting at a house in south Wisconsin, in the US.
Neighbours said they thought the gunshot sounds were fireworks
Police in the town of Delavan found the victims after responding to a call late on Saturday night.
The child was found shot in the chest in a car outside the house, a police spokeswoman said.
Although police provided little further information, AFP news agency says they seem to be treating the incident as a possible case of murder-suicide.
During a brief press conference, police chief Tim O'Neill said that the injured child was a two-year-old girl.
She is in a serious condition at the University of Wisconsin Hospital in Madison, he said.
AP reports that a 19-year-old woman, Vanessa Iverson, was one of the victims of the shooting.
Her sister-in-law said a family with three children lived in the house, including a set of twins as well as the two-year-old girl.
Police set up a cordon around the property, in a residential area some 45 miles (70km) south-west of Milwaukee.
Neighbours, many of whom had believed that the sound of gunshots was children playing with fireworks, watched as the bodies were wheeled out on Sunday morning.
