The suspects are plentiful when a lottery winner turns up dead.

When a bride falls to her death on her wedding day, the list of suspects is as long as the guest list, and it includes a jilted ex-boyfriend and an overbearing father. Meanwhile, Ethan's interest in new member Dani is not reciprocated, as she may have her eye on someone else on the team.

A murder investigation strikes close to home when an undercover policeman is killed execution-style at a truck stop.

Two young girls are in an auto accident, where one is critically injured and the other is pronounced dead. But Megan's team soon discovers that the victims' identities were mistaken, and the deceased may not have been killed in the crash.

An act of terrorism unleashes an unknown virus that kills scores of people throughout the city. The Center for Disease Control takes over the investigation to determine what caused the outbreak and uncover who was responsible.
