Negligence. Evidence, Presumptions and burden of proof. To sustain an action under R.L.c. 106, § 73, by the widow of an employee against his employer for causing the instantaneous death of her husband, the plaintiff must show affirmatively that her husband at the time of the accident causing his death was in the exercise of due care, and if there is an entire absence of evidence as to what he was doing when the accident happened a verdict must be ordered for the defendant.
KNOWLTON, C.J.
It is unnecessary to consider other parts of this case, for there is nothing to show that the plaintiff's husband, at the time of the accident, was in the exercise of due care. He was found dead on the floor of the engine room, in the passageway between the rapidly revolving fly wheel and the wall of the building. He was the engineer in charge of the engine, and no one else was present at the time of the accident. The top of his skull was cut off, and it seems likely that this was done by the fly wheel or some of its attachments. If it is possible that the accident happened while the deceased was in the exercise of due care, it is equally possible and more probable that his negligence was one of the causes, if not the sole cause, of his death. In Tyndale v. Old Colony Railroad, 156 Mass. 503, this court said: "Where there is an entire absence of evidence as to what the person killed was doing at the time of the accident, it is not enough to show that one conjecture is more probable than another. There must be some evidence to show that he was in the exercise of due care." Similar language is used in Gleason v. Worcester Consolidated Street Railway, 184 Mass. 290. See also Shea v. Boston Maine Railroad, 154 Mass. 31; Cox v. South Shore Boston Street Railway, 182 Mass. 497, 499; Irwin v. Alley, 158 Mass. 249; Felt v. Boston Maine Railroad, 161 Mass. 311; Mathes v. Lowell, Lawrence, Haverhill Street Railway, 177 Mass. 416; Murphy v. Boston Albany Railroad, 167 Mass. 64.
