The lives of four members of one family were snuffed out in a crossing accident at 2:55 Tuesday afternoon when eastbound Baltimore & Ohio passenger train No. 10 hit the Ford touring car, in which were riding Herman Clausen, 35, his half brother, Carl, 15, his brothers-in-law, Arthur Moehring, 23, and Dave Kinder, 22. The accident happened on the angling crossing, one mile and a half east of Hamler, within sight of the home of Mrs. M. Clausen.
