Drew Carey guest stars as a retired Marine Sergeant in NCIS season 15 episode 16, and he's going to need help from Gibbs and the team. In "Handle with Care," cyanide is found in one of the hundreds of care packages he sends to active-duty Marines, but can the team clear his name?

Check out a sneak peek of Carey guest starring as Marine Sergeant John Ross:

Here, we learn a bit about the care packages and see how Ross runs his operation. Each box includes photos from the person sending it, and the boxes aren't just going to people they know. (One man is sending a box to his wife's sister's youngest son, and his special touch is his wife's banana bread.)

Just as Ross is about to add cookies to his box, McGee and Torres interrupt. No, they're not there to help but to ask him some questions -- and these questions can't just be asked in front of everyone. One his care packages killed a sailor.

Find out more about Ross:

After going over Petty Officer Second Class James Sweeny's record (it's spotless), the team moves on to Ross, who sends out care packages every day. Are they sure Sweeney received one of his boxes? The contents are consistent with the packages he's sent in the past, and his pictures were inside. Gibbs notes that he has a Prisoner of War medal. He was held captive for five years in Iran.

Could retired Marine Sergeant John Ross really be a killer?
