Full name appears to be Peter Paul Strzok II. Can’t find any photos of him. There is an older Peter Paul Strzok a retired Army officer who perhaps is his father or uncle.
There is another purported (different guy) photo at http://www.zerohedge.com/news/2017-12-02/muellers-top-fbi-agent-probing-clinton-emails-russian-collusion-removed-after-anti-t
Being former .mil counterintel, he’s likely a ‘ghost’ online.
