What type of crime should people be on the lookout for?

All right, well, let's talk advice.

What are some ways that you can keep yourself safe from, say, pickpockets?

This doesn't really happen often, but you do hear about violence in the stands, from brawls to something more serious.

Any advice in dealing with those sorts of things?

And then there's just the risk of being with so many people in a confined space if you might need to get out quickly.

If you're going to a stadium with a child, how do you make sure they stay safe as well?

I remember years ago taking my kids to a circus and suddenly it was like, who has the little one?

I thought you had the little one.

You know, it was that moment of panic.

Well, this has been very, very helpful.

Vicki, thanks very much.

That's it for this episode of Dateline True Crime Weekly.

One final note before we go.

We wanted to bring you the latest on the search for Nancy Guthrie, the 84-year-old mother of our friend and colleague Savannah.

Investigators say Nancy was abducted from her Tucson, Arizona home in the early morning hours of February 1st.

On Monday, the Pima County Sheriff announced that all of Guthrie's family members, including the siblings and their spouses, have been cleared as possible suspects.

This comes a week after the FBI released the extraordinary footage recovered from Nancy's Nest security camera.

It showed a potential suspect in the case, a man the FBI estimates is of average build between 5'9 and 5'10 inches tall and was wearing an Ozark Trail hiker backpack.

If you have any information or tips about Nancy's disappearance, you can call the FBI tip line at 1-800-CALL-FBI.
