indeed it's a very sad news...and it's even more depressing now that the kidnappers have increased their randsom demand...
"A group that claims to have kidnapped two Japanese in Paraguay has again raised the ransom for their release to
$750,000, investigative sources said Wednesday. Making contact through a Paraguayan acquaintance of one of the hostages, Hirokazu Ota, the group has also warned that it will further boost the demand if preparation of the money takes time, the sources said."
