audio engineer for several years. Channel 4's Ashley Harding went to his Engelwood neighborhood... And has more on how his family is bringing attention to the case. 3 3 3 2036-411:08-1:23This empty lot on Mimosa Drive is marked only by grass, a wreath on the fence, and this Crimestoppers sign near the street.But the memory of what happened here one year ago is very real for Russ Levey. His father, Robert Levey, was murdered and his home set on fire.20:31--20:38 "There's not been an arrest made yet. We feel that, we're holding out hope that somebody knows something.Somebody in this neighborhood saw something." TRACK With that drive, Levey, along with volunteers with MAD DADS took to the streets. They knocked on doors and passed out fliers. Assisting in the mission was the family of Amber Bass, the 22 year old woman shot and killed in her driveway last year.Stuart Carson's family was there too. He was the Jacksonville cab driver killed two weeks ago. An arrest was made in his case this week. MAD DADS believes many more cases can be solved. 26:16--26:25 "We're going to continue to be out here on the streets.We're going to continue knocking on doors, handing out fliers until we catch them all. It's either all or none." TRACK Levey says although coping with his father's death over the last year has gotten easier, it doesn't erase the pain of knowing what happened to him. But it does fuel his family's push for answers. 21:30-- 21:37 "This individual needs to be found. He needs to get arrested. He needs to--he can have his day in court, but our family wants justice."
