An Ohio man was sentenced to 22 years behind bars after pleading guilty Tuesday to the fatal shooting of his youngest child.

Jamal Mansour, 64, murdered his daughter, Tahani Mansour, 27, as she slept, claiming his intent was due to her disrespecting 'his rules about coming home late' and refusing 'to clean up her room,' according to Cleveland.com.

The nightmare incident happened the night of September 27, 2016 at the family home in Rocky River following a domestic dispute about Tahani's messy bedroom.

The furious father of seven said his daughter often left 'piles of clothes all over the room and half-eaten meals left under her bed' after he ordered her to clean.

He cried in court saying: 'I hope that they can forgive me ... I miss her so much. I wish I was the one that was dead'

Back in 2012, Rocky River police were called to the home once before after he threatened suicide when his 'daughter was on a business trip in Las Vegas'

He told authorities after the killing he believed bringing out a weapon would teach his daughter to 'respect' him.

'I hope that they can forgive me ... I miss her so much. I wish I was the one that was dead,' he cried Tuesday during his sentencing, the local newspaper reported.

While Mansour does not hold a criminal history of abuse, police in Rocky River were called to the home once before after he threatened suicide because his 'daughter was on a business trip in Las Vegas.'

Mansour's defense attorney, Angelo Lonardo, said his client has been an 'ideal father' and worked hard to provide for his family as he owns gas stations across Northeast Ohio.

The prosecutor said when Tahani was with her secret boyfriend, 'she had to pretend like she was with other people' for fear of her father's reaction

But it seems his daughter's messiness wasn't the only thing he was unhappy about in the weeks leading up to her killing.

Other issues were addressed during investigation - one in particular regarding Tahani's secret dating life.

She was reportedly dating a man who did not have the same religious beliefs as the family. She was forced to keep their relationship private for fear of her father's reaction.

'She was worried about what would happen if he found out,' said Assistant Cuyahoga County Prosecutor Andrew Rogalski.

'When she was with him, she had to pretend like she was with other people.'

She died while undergoing emergency brain surgery following the shooting to her face and head

At the time of Mansour's deadly rage, he shot his daughter twice - once on the side of her face and once in the back of her head.

She died while undergoing emergency brain surgery following the trauma.

Mansour reportedly stayed at the home while she underwent surgery, when he admitted to police he shot her.

Cuyahoga County Common Pleas Judge, Nancy Margaret Russo, condemned Mansour, saying: 'I bet the last thing she worried about happening to her is being killed by her own father.'

During Tuesday's hearing, the crying father could be seen blowing kisses to family members across the court room and apologizing for his wrongdoing.

The late Tahani had a promising career working as a pharmacist at University Hospitals Ahuja Medical Center in Beachwood.
