The 28-year-old Krystian M., who is suspected, among other things, of directing the murder of crime reporter Peter R. de Vries, vented his frustrations Monday in the secure court at Schiphol Airport in another criminal case in which he is a suspect. An anonymous witness made a very incriminating statement about M., but according to him he is being "framed." "The witness set everything up himself. Smart move by him, checkmate," he bellowed. "Sorry, I'm frustrated," he told the judge.
