(CHICAGO) -- At least four people were killed and four others were injured Tuesday morning in the second mass shooting in Chicago in four days, police said.
A barrage of gunfire erupted just before 6 a.m. in the city's Englewood neighborhood, police said. The shooting followed a disturbance at a home, police said.
Several people were gathering inside the home when the shooting started, police said.
ABC station WLS-TV in Chicago confirmed through police sources that four people were pronounced dead at the scene. The names and ages of those killed were not immediately released.
Four people suffered critical injuries in the shooting, including a 25-year-old man and another male who were both shot in the back of the head, police told WLS.
A woman and a 23-year-old man, who was shot in the back, were also in critical condition at University of Chicago Hospital, police said.
Some of those hurt were taken to hospitals in private cars. A child was rushed to St. Bernard Hospital for observation, authorities said.
The motive and details of what prompted the shooting are under investigation.
The incident follows a mass shooting on Saturday in Chicago that left a woman dead and nine adults injured.
Chicago police officials said investigators are searching for two suspects who walked up to a crowd gathered on the sidewalk in a business district in Chicago's Chatham neighborhood and opened fire just after 2 a.m. on Saturday. The nine adults who suffered non-life-threatening injuries in the shooting ranged in age from 23 to 46, according to police.
The Cook County Medical Examiner identified Kimfier Miles, 29, as the woman killed in Saturday's mass shooting.
