For months after the murder, Nealy pretended she was alive by sending text messages and photos of their two young children to family on her behalf. However, officials said her family got suspicious, because they had not heard her voice. 

That's when, court officials said Nealy went to Tarpon Springs in December 2018 and killed her father, 71-year-old Richard Ivancic; her mother, 59-year-old Laura Ivancic; her brother, 25-year-old Nicholas Ivancic; and the three dogs in their home.

According to the court, prosecutors reduced the first-degree murder charge to manslaughter in the Pasco County murder of Jamie. He pleaded guilty to that charge and was sentenced to 30 years in prison.

Prosecutors said Nealy got five years in prison for each count of aggravated animal cruelty, which will run concurrent with each other, as well as the 30-year sentence for the Pasco murder.  

The penalty phase for the three Pinellas County murders he pleaded guilty to is scheduled to begin on October 14, 2024. Officials said jurors will be able to recommend life or the death penalty.
