Maryland Man Pleads Guilty to 2009 Killing of Clarendon Resident

A 20-year-old from Severn, Md., pleaded guilty to killing a Clarendon man Tuesday in an Arlington County Circuit Court, according to The Washington Post.

Roger K. Clark III was  in connection with a Dec. 29, 2009, homicide of Carl Diener, a 57-year-old Arlington resident, who was found  outside a health club.

Just a few days before his trial was set to begin, Clark pleaded guilty to first-degree murder.

In a county that recorded just one homicide in 2010, Diener’s death came as a shock to the community. Close family and friends collected about $25,000 for information that would lead to an arrest following the local man’s death. 

Lyon Village residents to remember Diener and reignite the search for his killer on the one-year anniversary of his death.
