One article described Stevens as a "bombshell" and she was a real looker in the pictures I saw. Her first husband, a B-17 gunner who spent time in a POW camp, divorced her for infidelity. One article reported a rumor that she was having an affair with the husband who owned the house where the shooting occured, Charles Milton.
Stevens, born in Texas, married an Army major in the airborne and ended up in Connecticut. The shooting happened around midnight and it appears everyone was intoxicated. The victim and his brother went to the Milton home to hang out with a girl who was some kind of helper to Mrs. Milton. Stevens said she thought they were burglars and went to investigate with a gun her husband had left her. She claimed the victim, who was a sailor in the submarine service, rushed her and she shot him in self defense. The witness stories varied, probably because everyone was drunk.
The prosecutor later gave up and dismissed the charges, concluding he could not overcome the self-defense claim.
The trail then disappeared and I couldn't find anything about what happened later to her or others involved in the case.
She married an obscure young Arkansas politician named Clintoon, and the rest is herstory.
