Ricky Ricardo Chiles III (pictured), who was suspected of fatally shooting two people, shot himself with his gun on Thursday morning . A man suspected of fatally shooting two people at the scene of a traffic accident that killed his nephew has taken his own life, according to police. Ricky Ricardo Chiles III, 27, killed himself with a single shot  as police closed in on him at the Presidential Inn & Suites in Lyon, Illinois on Thursday around 9am, said Milwaukee Police Chief Edward Flynn. Since Tuesday, police were looking for Chiles III in connection to the killing 40-year-old Archie Brown Jr and 15-year-old Rasheed Chiles. Brown struck and killed the gunman's two-year-old nephew Damani Terry after he darted into the street in front of Brown's van, authorities said. Damani's brother, Rasheed and also the nephew of Chiles III, was  struck by the gunfire at the scene of the accident. He later died at a hospital. Police believe Chiles III decided to exact revenge and took the law into his own hands. 'This sad example is what we get when we have folks who decide it's their responsibility to use their guns to redress their grievances,' said Flynn. On Wednesday around 7.30pm, Flynn said Milwaukee police obtained a warrant on for the arrest of Chiles III in connection to Sunday's shootings. He was with his girlfriend at the motel on Thursday, who has not been identified, and who was uninjured in the incident. Police said it is not clear if she will face any charges, according to the Journal Sentinel. Scroll down for video .

While at the scene an unidentified gunman shot Brown and Damani's 15-year-old brother, Rasheed Chiles (right) After being released from prison in August 2013 for serving a two year-conviction for a 2011 bank robbery where he was the getaway driver, Chiles III was on extended supervision at the time of the shooting on Sunday. He was also prohibited from possessing firearms. Chiles III had a previous criminal history which included convictions of disorderly conduct, resisting an officer and fourth-degree sexual assault. Police Captain Timothy Heier said the car accident occurred at 5.10pm on Sunday after little Damani ran into the street in a residential neighborhood on the 4600 block of North 48th Street in Milwaukee. Witnesses said on Sunday that Damani and Rasheed had been attending a birthday party when the accident and shootings took place. According to reports, Rasheed had brought his toddler brother to a house party Sunday, but the little boy got out of the house and darted into the street . When Damani was run over, Rasheed rushed outside to his aid, at which point someone opened fire. The teen was struck in the shoulder and later died during surgery .

Brown Jr, a father of four, was struck in the head by a bullet and died at the scene near a park on Milwaukee's near northwest side before officers arrived. Rasheed, who was caught in the crossfire, was hit in the shoulder and was taken to a hospital, where he died during surgery, according to police. The Milwaukee County Medical Examiner's Office confirmed in a statement late on Monday that Damani and Rasheed were brothers. A police statement said Brown Jr was distraught about hitting the child and stopped right away, according to witnesses. Mayor Tom Barrett called the shooting of Brown an 'assassination' during an earlier emotional press conference. 'Someone got angry,' Barrett said. 'Someone took a gun and basically assassinated this gentleman.' Milwaukee Police Chief Edward Flynn speaks to reporters on Thursday providing details related to Chiles III's suicide on Thursday morning . Above, the scene of a car accident in Milwaukee, Wilconsin on Sunday. Police saud they had obtained a warrant on Wednesday night for the arrest of Chiles III in connection with Sunday's shooting . A local alderman suggested that the shooting was carried out in revenge of the child's death . Following Thursday morning's incident, Brown's father, Archie Brown Sr, said Chiles III cheated himself out of being judged by a man's system where he would be incarcerated. 'He he took a way out that put him in a worse situation because now he went to meet his maker to answer for his crimes,' Brown Sr told the Journal Sentinel. On Wednesday, a vigil was held for Brown Jr as his wife as well as family and friends attended. Following the shooting, Barbara Sprewer, a witness, said she saw Damani looking around before crossing the street, apparently heading for some girls dancing in the nearby park. She saw the van approach, and estimated it was going 25 to 30mph. Archie Brown Sr, identified his son, father-of-four Archie Brown Jr, as the driver who was shot in the head and killed at the scene . 'Nobody was watching the baby,' she said. After the child was hit, she saw the driver get out. She said she heard shots but did not see who shot him or Rasheed. 'I feel helpless. I feel numb,' she said. 'I saw them alive, and I saw them deceased. I've been reliving this since I woke up.' Bob May, 68, another next-door neighbor, said he heard five gunshots as he was washing dishes and thought at first it was firecrackers going off in the park. He said he looked out to see the van with its door open and people talking on phones. May said his neighbors had moved in about six months earlier and he did not know them. Brown Sr said his son, a real estate entrepreneur and landlord, was a great father to his four daughters, including a six-month-old baby. 'He liked to laugh. He took good care of his children. He was an excellent father to his children,' Brown Sr said. Brown Jr's half brother Riles Rilley also spoke with the Journal Sentinel and said that the 40-year-old was the co-owner of Seven West nightclub. 'Just a good person all around. Never had any enemies. Always looking to do the right thing,' he said. The shootings are among a climbing number of violent deaths in Milwaukee this year. The city has counted 43 homicide victims so far this year, compared with 14 at the same point last year. 'There just seems to be a sensibility among a segment of the community that committing acts of violence in support of one's reputation to get revenge for a perceived slight, or for a perceived business dispute over illegal drugs, or to exact revenge is somehow approved,' said Flynn. 'And in that set of circumstances there's going to be not only tragedies, there's going to be dreadful mistakes.' Chiles III was with his girlfriend at the Presidential Inn and Suites Motel (file photo above) in Lyon, Illinois when police closed in on him. Authorities said it is not yet known whether she will face charges in connection to the incident .
