A police official with direct knowledge of the case told The Associated Press that the man recently sent out a rambling e-mail to his wife in which he contemplated suicide and said, "You will be transformed from gold digger to ash and rubble digger." The official spoke on condition of anonymity because the investigation is ongoing.
I discovered this entry when looking into the history of the location. Commander Robert McIlwaine also saw duty in Korea at the Battle of Inchon.
MERCHANT VESSEL SURVIVES FIVE AIR ATTACKS;
SHOOTS DOWN FOUR PLANES, PROBABLY TWO MORE
The story of how an American merchant vessel last January, ran the gauntlet of five air attacks in the Eastern Atlantic. and Mediterranean, during which the Navy gun crew commanded by Lieutenant (junior grade) Robert H. McIlwaine, U. S. N. R., of 34 East 62 Street, New York City, shot down four enemy planes and accounted for two more "probables", was told when the ship arrived recently at a United States port.
Although damaged by near misses and by a bomb which penetrated to its highly inflammable cargo but failed to explode, the vessel was able to keep position in the convoy and to discharge its cargo on schedule. Temporary repairs were made, and the vessel continued to do her job for many weeks before coming to the United States for permanent repairs.
