FREDERICK, Md. - A 41-year-old Army veteran and a teenager described as his stepson were arrested at a roadside rest stop Thursday for questioning in the three-week wave of deadly sniper attacks that have terrorized the Washington, D.C., area. A law enforcement source said a gun found in their car appeared to have the same caliber as the one used in the shootings.
The official said police also found a scope and a tripod in the car. Police were awaiting ballistics tests on the gun.
“We’re positive it’s these guys,” the official told The Associated Press on condition of anonymity.
The arrests — linked to a telephoned boast about a deadly Alabama robbery — raised hopes of a conclusion to the intensive and often frustrating investigation of the shootings that have killed 10 people and critically wounded three others since Oct. 2.
