How did the caller know this? Very convenient of him to have an untraceable phone.

There is no such thing as an "untraceable phone". The caller might have used a pay phone, but where the heck do you find those these days?

You buy "pay phones" at the grocery store these days ... those "disposable" pre-paid phones are effectively untraceable, in terms of who is using them; and in any case it's tough to trace cell calls to anything more than a particular cell (a large area).
