Three Way All-in Sees Gruissem Bust

We recently arrived at Table 3 to find three players all in preflop. We didn't see how the chips went in, but Keith Gipson was all in for 284,000 from under the gun, Philipp Gruissem was in late position and was all in for just over 1 million in chips and Greg Merson was all in from the small blind, having both his opponents well covered. Below is how the cards looked.

Merson:
Gruissem:
Gipson:

Gipson was looking good to double up and Gruissem was needing some help to stay alive. By the time the dealer spread out a board, Gipson had picked up 284,000 from both Gruissem and Merson’s stack, while Merson had taken Gruissem’s last 1 million in chips.
