Teammate gave him a suicide pass
Should he have passed it to him, no not really, however not really a classic suicide pass. Those generally involve a player moving up ice at a pretty nice clip of speed having to reach for the puck and/or look back causing him to get destroyed, not really what was going on here.
This guy receives the puck and heads up ice while not looking, the goalie should be screaming his lungs out as should the winger the D-man clearly thought the guy that buried him would stay on the half-wall with, but a decent amount of the onus is on the D-man himself for a careless turn up ice while performing a slow cradle to control the puck.
Suicide passes are more classically like the Gryba hit on Eller where Diaz sent him into just a horrendous area of the ice where he couldn't possible protect himself. The player here can let that pass by as it isn't traveling in the middle of the ice especially if his teammates are talking appropriately or quickly continue it on with backhand down the boards without attempting to cradle and shift up ice.
Also as pointed out above have to believe this was charging by the letter of the law, but would need a better angle.
