Cruel Killer Sentenced: 44 Years for Domestic Violence Murder (2026)

A Chilling Tale of Domestic Violence: Man Sentenced to Decades in Prison for Murder and Desecration

In a deeply disturbing case, Paul Jason Sultana, 35, has been sentenced to a maximum of 44 years in prison, with a non-parole period of 33 years, for the brutal murder of his partner, Dayna Isaac. The crime, which involved strangulation and the desecration of Isaac's body, has left the community reeling and highlights the pervasive issue of domestic violence.

The relationship between Sultana and Isaac was tumultuous, with Isaac expressing her desire for a less committed relationship. However, Sultana's inability to accept her wishes led to a series of events that ended in tragedy. On the day of the murder, he waited for her at her home in Penrith, Western Sydney, and, once inside, he shoved her, dragged her to the bedroom, and strangled her. The police discovered Isaac's body with her trousers and underwear pulled down, and forensic testing revealed Sultana's DNA on her groin area.

The severity of the crime is underscored by the judge's statement, 'Sheer terror is an appropriate description.' The premeditated nature of the attack, the persistent assaults, and the degradation of Isaac's body all contributed to the harsh sentence. Sultana's history of violent offenses and his time spent in prison since 2016 further emphasized the need for a severe punishment.

Despite being diagnosed with schizophrenia after his arrest, the court found no evidence linking his condition to the murder. Justice Garling described intimate domestic partner violence as a scourge in a civilized society, emphasizing the need for complete condemnation of such behavior. He stated, 'There is simply no place at all in our community for conduct of this kind. It must be marked with significant disapprobation.'

Sultana's trial revealed a denial of the murder, claiming he was asleep on the couch and that a third party was involved. However, the judge rejected this defense, finding him guilty. After the murder, Sultana destroyed Isaac's car by setting it on fire in a remote bushland area.

The case serves as a stark reminder of the dangers of domestic violence and the importance of taking such crimes seriously. It also highlights the need for support and resources for victims, with the provided contact information for organizations like 1800 RESPECT, Lifeline, and the Men's Referral Service offering assistance to those affected by such violence.
