Story highlights Officers circled the man, who was in a wheelchair, telling him to put his hands up 
 
 The chief says the man reached for the gun; his mother disputes this claim 
 
 (CNN) Police officers, their guns raised, approach the man in the wheelchair and yell out loudly and repeatedly: "Drop the gun" and "hands up." Video of the shooting posted online, which the chief said appeared to be authentic, shows an officer approaching McDole with a gun drawn, shouting "show me your hands" and "drop the gun." The man fidgets, moving his legs with his hands, rubbing his knees with both hands, trying to raise himself out of the wheelchair. Then he slides his hand up his thigh toward his waist and officers open fire. Several shots ring out. The officers, who are not in the video at this point, fire multiple shots and McDole falls out of his wheelchair. WARNING: Graphic video 
 
 On Thursday, a day after the shooting, Police Chief Bobby Cummings said Jeremy “Bam” McDole was armed and reaching for a weapon. McDole’s mother, Phyllis, said her son did not have a weapon and would never harm himself.

 The shooting happened on a narrow street in Wilmington on Wednesday around 3 p.m. Officers responded to a 911 call of a man who had shot himself, and when they arrived, 28-year-old Jeremy McDole was "still armed with a handgun," Police Chief Bobby Cummings said during a news conference. When officers arrived, he said, they located the man in the 1800 block of Tulip Street, where they repeatedly told him to put down his weapon and raise his arms.

 Instead, "when Mr. McDole began to remove the weapon from his waist, the officers engaged him," Cummings said. Cummings would not divulge the names or race of the officers involved in the shooting, or if any had any prior encounters with McDole. The four officers involved in the shooting have been placed on administrative leave. “I’m sorry for the officers and family of Mr. McDole, as this encounter unfortunately ended with the loss of his life,” said Cummings. “I know that this incident could impact police and community relations, therefore, I will ensure a thorough and transparent investigation will be conducted.” 
 
 The city police department has been working to improve relations with its residents in the past year. The shooting is being investigated by the department's criminal investigation and professional standards units, as well as the Delaware Department of Justice's Office of Civil Rights and Public Trust, which will determine whether any officers will be charged. He also would not say whether he thought the situation should have been handled differently. McDole's uncle, Eugene Smith, was among a crowd of a couple dozen people who gathered Thursday at the scene of the shooting. Cummings said he was not aware of any attempt by officers to use nonlethal force before shooting McDole. A bouquet of flowers was placed at the scene and some gray powder was on the concrete, apparently to soak up bloodstains. Richard Smith, head of the Delaware chapter of the NAACP, called for a special prosecutor to investigate the shooting, and "to not have cops investigating cops." He said police officers can’t be investigating police officers in the same city. At this point, the city and the state need closure, Smith said. They have a right to breathe.” 
 
 McDole was paralyzed from the waist down after he was shot in the back about 10 years ago and was living at the Hillside Center nursing home on the 800 block of South Broom Street, according to McDole’s great uncle, Vincent Smith. “We want justice for my brother,” Ashley Morrison-Wright, 23, of Wilmington, said Thursday. “The mayor’s office and police department is aware of the video footage,” city spokeswoman Alexandra Coppadge said, “and will continue to conduct a thorough investigation of the officer-involved shooting.” 
 
 Anthony Slaughter is a friend and mentor to McDole who said he met with him just a few days before his death. Police said a .38-caliber gun was found by McDole's side after he was shot. Read or Share this story: http://delonline.us/1Fi5Aps
– Angry relatives are calling it an "execution." Jeremy McDole, a 28-year-old man paralyzed from the waist down, was shot dead in his wheelchair on a street in Wilmington, Del., the News Journal reports. Police say they received a 911 call Wednesday afternoon about a man who had shot himself with a handgun and McDole was still armed when they arrived, reports CNN. The city's chief of police say McDole was ordered to put his hands up and when he "began to remove the weapon from his waist, the officers engaged him" and fired the fatal shots. The four officers involved have been placed on leave while the shooting is investigated. Video of the encounter posted on YouTube shows officers shouting at McDole to drop his weapon, although the .38 handgun police say they found isn't visible in the video. Relatives, including McDole's mother, say he never had a weapon, the News Journal reports. "This was murder," she told reporters. "He shot my son like he was roadkill." An uncle calls it an "execution" and says he was with McDole 15 minutes earlier and didn't see a gun. McDole—who was paralyzed after being shot in the back in 2005—was black; police have not disclosed the race of the four officers involved. Last night, Wilmington Mayor Dennis Williams and Delaware Gov. Jack Markell visited a vigil outside the home of McDole's mother and promised that the family would get answers, the AP reports.
