how do I locate the owner of a private domain

You either can contact the registrar by phone or if you check a "Whois",
the registrar will show the owner's email with something like:
"proxy611536@1and1-private-registration.com"
You can send the owner an email.

Yup , email the whois email associated with it , it should forward to the owner's actual email , else if it's a major issue - try contacting the registrar.
