The state's key witness in the Bar Noar murder case slipped out of the bedroom window of his safe house late Wednesday night and disappeared without a trace, sending police scrambling across the Tel Aviv area to find him.National Police Commissioner Yohanan Danino has appointed a committee of inquiry to examine how the man managed to slip away from the police officers securing the safe house.After he fled, the witness was gone for several hours before detectives discovered he was missing, and by Thursday afternoon police said they still have not located him and are using all the means at their disposal in the search. There is some fear that the man may try to flee the country, and police have notified airport authorities.
