track down the kidnapper [by, with] the hostage's GPS info

Dear all,

The police tracked down the kidnapper [by, with] the hostage's GPS information.

I made it up. Could you tell me which of "by" or "with" would suit this sentence?

"The police tracked down the kidnapper with the hostage's GPS information."

"By" would only work in conjunction with the verb "using". For example, "The police tracked down the kidnapper by using the hostage's GPS information."

 

[perpend]

Both "by" and "with" work in AmE.

You can skip the preposition altogether: ... down the kidnapper using the hostage's ....

 

[tehtmc]

You can skip the preposition altogether: ... down the kidnapper using the hostage's ....

This sounds more natural to me.

Thank you very much, Binkadin, perpend, and tehtmc!
