Ross, said he buried the wealthy widow after mur dering her in Los Angeles. The body was located 21 miles east of Gorman on the road to Palmdale. LOS ANGELES, May 21. (UP)—A man with a “doodle-bag” came to the aid today of police who have a supposed confession to the “trunk murder” of Mrs. Leona Schmidt, 59, but cannot find her body buried in the sandy wastes of the Mojave desert. Roger S. Adams, the “doodle-bug”’ man, claims his device will point to buried metals. Detectives hoped it might react to the nails and heel caps in Mrs. Schmidt's shoes, or to jewelry buried with her body. To Cover Desert, Officers who have poked and dug in the sands with shovels and prob ing irons for three days, planned to take Adams with them to the desert today. He was to make his ‘“doodle bug” back and forth over the barren stretch 100 miles away from Los An geles where Walien Neil Ross says he buried his mother-in-law last March 9 after shooting her to death.
