Brunswick , Georgia ( CNN ) -- The investigation into the shooting of a baby in Brunswick , Georgia -- a crime that 's grabbed national headlines -- has taken yet another turn with the arrest of a local politician . The arrest stemmed from a verbal exchange between Brunswick City Commissioner James Henry Brooks and the family of one of the teen suspects in the slaying during the suspects ' first court appearance on Monday . According to his attorney , Brooks told the family of De'Marquise Elkins , 17 , that they did n't have to talk to police . `` What he was trying to do , at the point and time that he was approached here at the courthouse , was just tell these folks you have a right to remain silent , '' Brooks ' attorney Alan Tucker told reporters Friday . Brooks is a distant relative of the Elkins family , his wife , Alicia Brooks , told CNN . She did not know exactly how they are related . The 59-year-old commissioner was charged with influencing a witness and obstructing law enforcement in an investigation , the Glynn County Sheriff 's Office said . Brooks was arrested Thursday , posted $ 5,000 bond and left jail Friday afternoon . Tucker said his client was not trying to interfere with the investigation . `` I do n't know why he spoke with the Elkins family other than the fact that they are constituents of his , '' the attorney said . `` The public defender 's office put a statement out earlier in the week , and I think that there were many people in the community who maybe thought that these two young men had not committed the crime with which they are charged with , and evidence has come to light and the gun was found . '' Under the terms of his bond , Brooks is not allowed to have any contact with the victims , witnesses , potential witnesses or investigators involved in the investigation of the murder of 13-month-old Antonio Santiago , who was killed March 21 . The child 's mother , Sherry West , has said that two teenagers came up to her in the street in broad daylight . One pointed a gun at her and told her that if she did n't give him her money he would shoot her and shoot her baby . West said that the teen fired at her , hitting her in one leg and barely missing her head . The teen , she said , then shot her baby in the face . Elkins and Dominique Lang , 15 , have been charged with murder . Elkins ' mother , aunt and sister have also been arrested on various charges alleging that they have hindered the investigation . The sister , 19-year-old Sabrina Elkins , was arrested on an evidence tampering charge , the Glynn County Sheriff 's Office said . She was named in a grand jury indictment , released Wednesday , accusing her of helping her mother get rid of the gun authorities say was used to kill the child . Authorities did not reveal her alleged role in disposing of the gun , which police found in a pond 2.3 miles from where the baby was shot . Baby 's death marks second time mom loses a son to violence . Sabrina Elkins `` was part of that , and that 's the most I can answer of that question right now , '' Glynn County Police Chief Matt Doering said Thursday . The grand jury also indicted Elkins ' mother , Karimah Aisha Elkins , 36 , and aunt , Katrina Latrelle Elkins , 33 , on charges of making false statements or writings , among other things . Elkin 's mother , Karimah Aisha , and his sister , Sabrina , made their first court appearance Friday and were ordered held without bond , according to Ron Corbett , the Glynn County 's undersheriff . None of the women is accused of involvement in the shooting itself . The same grand jury that indicted the women also named De'Marquise Elkins and Lang as being involved in the shooting , prosecutors said . Elkins is accused of malice and felony murder , along with other charges . Lang is accused of felony murder . Although Lang is a minor , CNN is identifying him because he is charged as an adult and media in the community have been naming him since his arrest . Investigators are looking into the possibility of a gang tie to the shooting , Doering said . `` That 's being explored , whether a gang involvement was part of this , '' he said . `` And that 's all that I can say right now . '' Doering declined to say whether more arrests were possible as the investigation continues . West gave this account to police about the shooting : . One of the boys pointed a gun at her and said , `` 'Give me your money or I 'm going to kill you and I 'm going to shoot your baby and kill your baby . ' '' The boy tried to grab her purse and opened fire when she told him she had no money . One shot hit her in the leg and one grazed her head . The boy then shot the child . West tried to resuscitate her son as bystanders called 911 for help . Mom to teenage son accused in baby shooting : ' I love you ' CNN 's Chelsea J. Carter , Joe Sutton , Victor Blackwell , Paul Caron and Chuck Johnston contributed to this report .
