Mr. Byrd had been stabbed in the mid-torso and was taken by ambulance to a Baltimore hospital, where he died.
There was no indication at the time that the stabbing was gang or drug-related.
Police said in January 2008 that the man suspected of stabbing Mr. Byrd to death was incarcerated on unrelated charges and expected to be charged in connection with Mr. Byrd's death.
Staniewicz confirmed last week there is a person of interest in the case who remains incarcerated. No one has been charged in connection with stabbing Mr. Byrd.
Mr. Byrd also had contacts with the criminal justice system, including several drug-related charges.
Anyone with information is asked to contact Det. Tom Walsh at 410-836-5408.
Lewis and Goodson
Two brothers were shot and killed in an Edgewood condo in 2006 and their killer or killers remain at large.
Randolph Mendon Goodson, who was 30 according to police and 28 according to his obituary, and his brother, Waverly Corey Lewis, 19, were found dead in a condo in the 1300 block of Goldmeadow Way Sept. 14, 2006 by a relative who stopped by to visit them.
Both men were born in Brooklyn, N.Y., and while a police press release said both had been living in Edgewood for more than a year, the obituaries for the two men said Mr. Lewis was from Edgewood and Mr. Goodson was still a resident of Brooklyn.
Police said the two men had been targeted.
In 2003, when he was 16, Mr. Lewis was allegedly involved in a drive-by shooting in Havre de Grace that wounded two teenagers. The shooting took place at the intersection of Girard and Stokes streets, which at the time was a notorious drug corners.
Mr. Lewis was charged as an adult with two counts of attempted first-degree murder, two counts of first-degree assault, use of a handgun in commission of a violent crime and reckless endangerment in a car. Mr. Lewis was indicted on the charges, but the case was ultimately dropped.
He has also faced disorderly conduct and drug possession charges in other cases.
Anyone with information about the murders of Mr. Lewis and Mr. Goodson are asked to contact Det. Walsh at 410-836-5408.
