Don't nag your big brother in Chicago. You might not live to nag another day:

Richard Bubacz, 65, is charged with first-degree murder in the death of Rita Bubacz, 61, who lived with her brother in an apartment in the 2400 block of West Albion Street, prosecutors said.

The accused allegedly used a hammer and knife to kill his sister Sunday, prosecutors said in court Wednesday at 26th and California.

After the slaying, Bubacz allegedly called 911 and told the dispatcher his sister had killed herself. When paramedics arrived, Bubacz allegedly revealed stab wounds to his own chest, neck, genitals and abdomen, and explained he had tried to kill himself, prosecutors said.

Rita Bubacz was found slain in her bedroom, prosecutors said. Richard Bubacz later admitted to police and paramedics that he had killed his sister because she had been nagging and complaining.
