( CNN ) -- Answers remain in short supply as to why an unarmed teenager was shot and killed two weeks ago . Trayvon Martin , 17 , was walking toward the home of his father 's fiancee in a gated community in Sanford , Florida , around sunset on February 26 . The neighborhood watch captain , 28-year-old George Zimmerman , saw the teen on the property and called 911 . According to CNN affiliate WFTV , Zimmerman , who is white , described Martin to a dispatcher as a suspicious black man . Sanford Police Chief Bill Lee said the 911 dispatcher told Zimmerman not to confront Martin , but by the time police arrived , the teenager lay dead with a gunshot wound in the chest . He was carrying a small amount of cash , some candy and an iced tea . Zimmerman told police he shot Martin in self-defense , but that does n't sit well with Martin 's parents . `` When you add it up , it just does n't even make sense , '' said Ben Crump , the Martin family 's attorney . `` Trayvon Martin , a kid , has a bag of Skittles . ( Zimmerman ) had a 9 mm gun . Trayvon Martin did n't approach George Zimmerman , George Zimmerman approached Trayvon Martin . So how can he now assert self-defense ? '' Police say a gunshot can be heard on the 911 calls recorded that night . Sanford police said Monday the calls will not be made public until the investigation is complete , but the Martin family is pushing for the tapes to be released sooner . `` It will tell us why ( Zimmerman ) just disregarded , just ignored the police instructions when they tell him to stay put , they 'll be there in a few minutes . On those 911 tapes is going to tell you why he said he 's not going to follow their instructions . And most importantly , it 's going to tell us his mentality when he confronted this 17-year-old kid , '' Crump said . Numerous attempts to contact Zimmerman by CNN were unsuccessful , and it is unclear whether Zimmerman has retained an attorney . Under intense pressure from the community , city officials in Sanford held a press conference on Monday . `` We are going to complete a thorough and fair investigation and present all the information to the state attorney 's office so justice can be rendered , '' Lee said . Police said they have not charged Zimmerman because there are no grounds to disprove his story of what happened . `` The evidence and testimony we have so far does not establish that Mr. Zimmerman did not act in self-defense . We do n't have anything to dispute his claim of self-defense , at this point , with the evidence and testimony that we have , '' Lee said . Lee said the directions the 911 dispatcher gave Zimmerman to not accost Martin when the incident arose were not mandatory instructions . `` That is a call taker making a recommendation to him . He 's not under a legal obligation to do that , so that is not something we can charge him with . But it would have been a good outcome ... if Trayvon Martin and George Zimmerman never came in contact with one another . '' Tensions are swelling in the black community over why Zimmerman is free . `` You 've got a little dead black boy , and the community sees you protecting the shooter , '' one man said . An outraged woman said , `` I 'm sure you 've heard the phrase , taking candy from a baby ? But this person , I 'm talking about every child , not just Trayvon Martin , whether he 's black , white , blue , yellow or green , it is easy to take a candy from a baby . It 's been said over and over and over again , but this person did n't take the candy , he took the life and left the child . '' Sanford City Manager Norton Bonaparte said he had personally extended condolences to the Martin family . `` We see this as a tragedy . We are doing a full and thorough investigation , and certainly the guilty parties ... will be punished . ''
