Eyewitness

Malloy and Reed search for a six-year-old boy who was apparently abducted while walking home from school, and later fear that an elderly witness's wildly inaccurate account may actually pertain to a different crime. They also respond to a barking dog complaint and become suspicious of the dog's owner, mediate a domestic dispute caused by a husband's obsession with watching football, respond to a very creative college prank and pursue armed robbery suspects through a crowded train depot with the aid of a police helicopter.
