An argument over unprotected sex allegedly led to the death of a Chicago high school teacher, according to the Daily Southtown.
The trial of an Ohio woman accused of killing him started Tuesday.
Alisha Walker, an accused prostitute, is charged with killing Al Filan, 61, two years ago after they met online.
The Daily Southtown reports that walker went to Filan's home with another prostitute after he solicited her for sex.
When the two did not agree to have unprotected sex, the Brother Rice High School teacher became violent.
Walker's lawyer says she killed Filan but it was in self-defense.
