An incarcerated man was charged with murder in connection with a 20-year-old fatal stabbing in Edgewood, according to the Harford County Sheriff's Office. 

Gary Williams was determined to be a person of interest during the initial investigation into the 2007 cold case. However, it wasn't until a witness came forward recently with new information that deputies were able to charge him. 

2007 murder cold case

On August 26, 2007, deputies responded to the 1900 block of Edgewater Drive for a stabbing. 

A man named David Arnold Byrd Jr. was found suffering from a single stab wound to his upper body. He was taken to a hospital where he later died from his injuries, officials said. 

During the initial investigation, deputies identified Williams as a person of interest, but were unable to gather enough evidence to formally charge him with a crime. 

Recently, deputies said a witness came forward with new information. The witness's account was deemed credible and provided the necessary evidence for investigators to pursue charges against Williams. 

Williams was indicted on charges related to Byrd's murder, and a warrant was issued for his arrest, deputies said.

 According to deputies, Williams is currently in the custody of the Federal Bureau of Prisons, serving a sentence for an unrelated crime. Once he is released, Williams will be taken into custody by Harford County Sheriff's officials.
