Arlington County Police have arrested Roger Clark III of Severn, Maryland and Javon Martin of Washington, D.C. and charged them in the killing of 57-year-old Carl Diener.
Diener's death on Dec. 29, 2009 shook the usually quiet, suburban neighborhood. Police found Diener lying stabbed in the street at around 2:50 a.m. that morning, likely as he was on his way to work at a gym on North Kirkwood street.
Officials don't believe Diener knew his attackers, according to a release from the department.
The Washington Field Office of the Federal Bureau of Investigation, the United States Marshals Service, the Montgomery County Police Department and the Metropolitan Police Department all participated in the investigation, according to a statement from ACPD. The suspects are awaiting extradition to Virginia.
