UNCANNY X-MEN #281 (OCT 91)
Sentinels attack the Reavers' base in Australia. They kill them, but they are primarily after Donald Pierce. Meanwhile, the X-Men are invited to a party by Emma Frost. When the X-Men arrive there are some hostilities between them and the Hellions. Soon, however, Trevor Fitzroy attacks, quickly killing Beef and Jetstream. The X-Men then fight him, but find him a match for them. Meanwhile Pierce runs to Gateway and tells him to teleport him to whoever is responsible for the Sentinels. The portal opens to where the X-Men are and the Sentinels attack them as well. One kills Tarot, another knocks down Emma Frost. Jean Grey is struck down also. When the fight is almost over, the Sentinels destroyed, the X-Men claim that Jean Grey is dead.
