Arrested for kidnapping.
Name appears to be Poman Zvonko.
Mugshot and further details are posted in Emerson Hauser's census room, as well as in Diego Soto's Inmates of Alcatraz.
Note: Poman Zvonko's mugshot appeared briefly in a promo prior to the airing of "Pilot".
Despite that, Thomas Madsen was listed in the episode as inmate #2002, and so Zvonko's number was an error.
