Specifically, the centre engine relit, but the outer two did not, for the 
intended 3-engine landing burn.  End result was 300mph impact with the water.

Musk said that they ran out of “boron”, which I assume means the TEA/TEB that 
the Merlin uses for ignition.

(See roughly 16:50 into the press conference.  The audio quality is poor, but I 
think “boron” was the key, rather than the actual propellant).
