What is the multisig address that the escrow funds were being held in?  It should be public, and each withdrawal should be able to be accounted for and described by Lauda as well as the 2nd signer for the multisig wallet.  These are pretty basic requirements for an escrow and the blockchain exists as a public record to check/balance what these individuals are claiming.  There should be no room for questioning, especially when this amount of funds are involved.
