Percey Jordan was searching for a victim the night he found retired New York Times journalist strolling alone in his Northwest Washington neighborhood, Assistant U.S. Attorney told a jury Monday during final arguments.

Jordan, 42, is charged with murder and robbery in the brutal beating death of David Rosenbaum in Grammercy Park in January. Jordan’s cousin Michael Hamlin pleaded guilty last month to murder and robbery and testified Thursday to the events that led to Rosenbaum’s death.
