Three teenagers charged in a July 4 fatal shooting in Englewood were seen brandishing guns and were asked to leave by multiple people in the area hours before the attack in front of a home, prosecutors said.Eugene Sanders and Dajon Neely, both 18, and a boy whose age wasn’t released, arrived around 9:50 p.m. July 3 in the 6200 block of South Laflin Street, where they are known to some neighbors because of family living in the area, according to a Cook County court document detailing their alleged roles in the fatal shooting of Dion Butler, 34.The three of them immediately approached a house where Butler’s two sisters answered the door but they soon left and hung out near the street. Sanders took videos of him, Neely and the boy in which they’re each seen holding firearms with extended magazines, the document said.They later roamed the block and pulled on car door handles. One person confronted them “because children were out on the block,” but they ignored their call to put the firearms away, the document said.Prosecutors said Butler and his girlfriend arrived in the area around 11:45 p.m. Butler, of the same block on Laflin Street and whose family knows Sanders, Neely and the boy, greeted them before he and his girlfriend went across the street and stood by a porch.Shortly after, other neighbors told Sanders, Neely and the boy to leave “because their actions were bringing too much attention to the area,” the document states.By around 1 a.m. July 4, Sanders, Neely and the boy walked to the home where Butler and his girlfriend were still sitting outside, but a woman who lived there told them to leave. They stayed around the porch steps while Sanders confronted Butler, asking him why his girlfriend was “giving him a strange look,” the document alleges.After Butler told Sanders he should ask his girlfriend himself, Sanders, Neely and the boy each pulled out guns and opened fire, prosecutors said.Butler, who did not have a weapon on him and who witnesses said “never made any threatening remarks or gestures,” suffered gunshot wounds to his head, neck, shoulder, arm, back, buttocks and both legs, prosecutors said. He was pronounced dead at 1:21 a.m. at University of Chicago Medical Center.Police recovered 17 shell casings from three separate guns at the scene, prosecutors said.Sanders, Neely and the boy ran from the scene northbound to another home on the same block. They fled from that home through a backyard about 15 minutes later and went to the boy’s aunt’s home about a block away on Justine Street, according to the document. While Butler’s sister drove to the hospital, she saw the alleged shooters exit the home on Justine Street and enter a car before they sped off.The boy was arrested in October in Kankakee, while Sanders and Neely were both arrested Tuesday in downstate Carbondale, according to prosecutors and police. They are each charged with first-degree murder.Sanders, of the 6100 block of South Marshfield Avenue, and Neely, of the 10900 block of South Church Street, were both ordered detained during a court hearing Thursday. They both face a Feb. 11 court date.The boy’s court information is not available.
