I can't imagine what she would have done if he forgot to come home with carton of milk she asked for...

I'm not sure if she was mad about the beer being warm or it being Stag Beer. From the St. Louis Post-Dispatch:

ST. LOUIS: Warm beer led to killing, police say

A St. Louis man was shot to death Sunday night over a warm beer, police said.

St. Louis police say a woman shot her husband, who was about 70 years old, four to five times in the chest after he tried giving her a warm can of Stag beer.

Police said the wife admitted shooting him about 5:40 p.m. in the kitchen of their home in the 5100 block of Terry Avenue. Police said the home had no electricity at the time.

Homicide detectives would not identify the man. The woman, whom police also did not identify, was taken into custody.

Obviously, there was more to the story.
