Well, there seems to have been a break in the case after all this time. The identity of one of his alleged killers has been uncovered by the Dubai police. Unfortunately for Dubai's gendarmes, the man has been dead since 1973.
The Jerusalem Post, citing a story in the Wall Street Journal, writes,
Sounds like something out of the French Revolution segment of History of the World, Part I. Mel Brooks fans will know what I mean.
“In cooperation with Interpol, British and French police, Dubai police were on
the trail of one of the alleged assassins of senior Hamas terrorist Mahmoud
al-Mabhouh. The man reportedly entered Dubai under a British passport with the
name "Christopher Lockwood." However, they discovered that the man's "real" name was Yehuda Lustig and that he had changed it in 1994 to the more Anglicized
"Christopher Lockwood," according to the Journal's report.”
“According to the Defense Ministry, the real Lustig died in a battle along the Suez Canal during the war, as yet another lead pursued by Dubai police chief Lt.-Gen. Dahi Khalfan Tamim leads to a dead end.”
