3 A grass roots push continues to solve unsolved murders here in Jacksonville .. including the killing of 22-year old Amber Bass .. she was gunned down in her driveway 4 months ago today. Still no arrests have been made. The scene of the crime was the family's home on Springtree Road -- near the intersection of Foreaker and Old Middleburg roads on the westside. Today, the victim's friends held up signs in front of the Duval County courthouse -- hoping the publicity will produce a tip that will lead to the killer. Channel 4's Ashley Harding spoke with those friends and joins us live from the courthouse, Ashley? 3 3 3 3 00-0620-2627-351:27-1:36PKG: TRACK Pete Singer spends the day outside the Duval County courthouse, hoping the signs he and his wife carry might touch someone, and lead to an arrest in the murder of their friend Amber Bass.This is Singer's birthday, but more importantly in his heart, it was four months ago today the young woman was gunned down in her own driveway."I just continually think about her everyday. You know, whenever I can go out and do something for her. Go out and help other families....I will always want to do that." "it hurts like the very first day still.I'm fighting back tears as we speak. I can't tell you how much she's missed."TRACK The Singers say the pain of not knowing is hard enough...they say Amber's family recently got the news from detectives that all leads in the case had dried up. That any NEW leads must come from the community. "that was such a kick in the gut. You don't want to know that nobody's looking anymore."TRACK Even though Amber's case is especially close to their hearts, they don't want the dozens of other unsolved cases to be forgotten. Cases like that of Michael Siegrist, who was killed trying to intervene in a robbery at a bus stop back in July. And 83-year old Robert Levy, who was found murdered in his burning home in Englewood last June.And Thomas Michael Kirby, a JTA bus driver whose body was found in front of an abandoned home. I talked to our crime expert Ken Jefferson, who says it's important as ever to bring justice to all grieving families."someone knows something, and they're just not divulging this information now.You can imagine the wit's end that the families are feeling now because there's been no progress. 3 3 3 3 Ashley, we saw Amber's friends were there.What about her family, were you able to talk to them today?Answer: Mary, unfortunately they were not available today.
