Deputies said they arrived and found Dinanno's husband -- 57-year-old Henry Joseph Breaux -- shot to death inside the home.
Dinanno was transported to an area hospital where she refused treatment, officials said. They then took her to the HCSO homicide unit for a statement.
The scene investigation contradicted Dinanno's statement, according to authorities, and she was charged with the murder of Breaux.? ?
Dinanno, 59, was being held Monday at Harris County Jail on $100,000 bond. She was slated to appear in the 232nd district court Tuesday.
