 Why did Tiger die?
As he did so the baby's knees hit the side of the play pen and young Laughton let out a scream—half from hurt and half from sudden lack of confidence in his new handler. Once inside, Nancy slammed the door, gave the baby to the stunned Martin and headed for the telephone. The car roared up the street, swerved toward the parkway, tires screaming, bounced over the curb and sidewalk, straight toward the child and mother. The mother was hit and instantly killed, force of the blow snapping her spine and tossing her against the house. The car plunged on into a tree, hitting it a terrible blow, crumbling the car's forward end so it looked like an accordion.
 Tiger suffocated.
 Tiger died from an allergic reaction to biting Arvid 6.  Tiger was poisoned.  Tiger suffocated.  Arvid 6 kicked Tiger to death.
