Cindy, I checked the Evening World Herald, April 11, 1921 on microfilm at the Omaha downtown library.Indeed, Joseph Howard was shot by a dective while fleeing a "soft drink parlor".I copied the front page story and would be happy to mail it to you.It includes pictures of the victims, a sketch of the crime area and car, and the dectective.
Here is a portion of the article: "Herdzina, in plain clothes, noticed the party was making a disturbance, he said, and he jumped onto the running board and commanded the driver to halt...Occupants of the car then tried to drag him inside, the detective claims, and someone hit him over the head with a beer bottle...'We had been drinking beer on the street,' said, Hannon, who admits beign at the wheel. 'We had about five gallons, I think.' Hannon said he knew nothing following the fight until he awoke in the South Side jail."It goes on quite a bit with lots of details.
The other articles are interesting, too.Included is a story of the "longest telephone conversation in the length of miles in the history of the world, covering a distance of 5,762 miles" - President Harding was calling Cuba and the Catalina Islands.Another headline is "Conquer Burglar with Army Shoe and Meat Knife - Husband breaks out of clothes closet and defends wife" Can you believe it?! The papers used much more artistic language then! :)
