Fairfax County police said Tuesday that two men have been charged with involuntary manslaughter in separate fatal crashes that happened earlier this year.

Police said 21-year-old Joseph Shuttleworth, of Alexandria, was charged in an alleged drunk-driving crash that killed his passenger, Adrian Cardozo, 21, on Feb. 15. The crash happened at about 2:10 a.m. on Franconia Road near Guilford Drive when Suttleworth struck a utility pole after driving around a curve at a high speed, police said.
