I'm trying to locate a 237 woman he was once involved with.

Or would they try to locate her by other means?

I've spent a great deal of time and money trying to locate him.

He's working with the state to try to locate where the other people are.

We're still trying to locate some member of his family, but so far without success.

He's trying to locate someone who might have been a student here.

He tried again to locate any of the others, but still couldn't see them.

What are we going to do about trying to locate her?

He must try to locate at least one of them.

We're trying to locate each and every one of them.
