A wealthy Ohio businessman of Jordanian descent who admits to fatally shooting his daughter at their family's suburban Cleveland home has been indicted on an aggravated murder charge.

Jamal Mansour, 63, told Rocky River police he was angry when he shot 27-year-old Tahani Mansour during a heated argument. The indictment was handed up Wednesday.

Mansour, a married father-of-six and a grandfather, is being held on a $4.5million bond. He is due back in court for his arraignment on October 20.

At his initial court appearance last week, City Prosecutor Michael O'Shea said Jamal 'executed' his own daughter and called her death 'an assassination,' but would not elaborate.

The prosecutor's description of the killing has raised the suggestion that it might have been an honor killing, but the suspect's attorney, Angelo Lenardo, vehemently denied it, saying the very notion was 'racist and offensive.'

'Mr. Mansour is a good man who very much loves his family,' Lenardo said of his client.

Authorities have not disclosed why Jamal became so enraged that he grabbed a gun and fired three rounds at his youngest child, hitting her twice in the head. After his arrest, he told a judge it was an accident.

The youngest of six children, Tahani was described by friends as bright and energetic, and had recently been hired as a clinical pharmacist by the Cleveland Clinic.

She received a doctor of pharmacy degree from Northeast Ohio Medical University in 2013, worked as a clinical pharmacist for University Hospitals and taught at the University of Findlay and the medical school, according to her LinkedIn account.

Tahani’s former classmate Philip King recalled how beautiful her smile was, how much she embraced the challenges of the rigorous program and how she enjoyed going out with friends.

‘She liked to be around people,’ King said.

King said her life at school and time with her friends allowed her to enjoy a measure of freedom she might not have had at home, where her family was ‘very, very protective’ of her.

‘It seemed to me like it was almost an escape,’ King said.

Tahani dated a classmate for two years during school, King revealed, a relationship he thinks she tried to hide from some of her family members.

King said she confided in him that she had some fear of her father, but he didn't press for details.

‘I didn't ask,’ King said. ‘I knew there were cultural reasons.’

Timothy Ulbrich taught Tahani all four years she attended NEOMED and helped her get appointed to a one-year hospital residency program she would need to be hired as a clinical pharmacist, a position where she would be working with teams of doctors and their patients in a hospital setting.

‘She was loud and she was energetic,’ Ulbrich said. ‘She had a personality that was just contagious to be around.’

Her father Jamal was born in Jordan and came to the US in 1978, eventually becoming an American citizen.

In 1993, he and wife Sumaya bought their home in Rocky River, a west side suburb popular among professionals.

Jamal comes from a well-to-do family who own gas stations and grocery stores in Ohio. He had recently returned from Jerusalem, where his family is building an apartment complex.

Justin Withrow, one of Jamal's attorneys, said in court last Thursday that his client is ‘devastated’ by his daughter's death and called the fatal shooting a ‘tragic situation.’

Police officers arrived at the Mansour family's home in the 22600 block of Vine Court in Rocky River after getting a frantic 911 call from the victim’s brother, reported Cleveland.com.

Tahani's sibling told a dispatcher that at around 1.15am, their father, Jamal, shot the young woman twice in the head in her upstairs bedroom.

The brother described Tahani as unconscious and breathing, but said her face was covered in blood and she was twitching.

On the 911 call, the brother also mentioned that his father was diabetic, but Lt. George Lichman, of the Rocky River Police, later disputed that claim, saying that paramedics who examined Jamal found that he was not 'under any medical care.'

Officers who responded to the scene found Tahani with two bullet wounds, including one to the front of her head. She was rushed to Fairview General Hospital, where she succumbed to her injuries 10 hours later.

While investigators say they are still searching for a motive, records show that Jamal had previously threatened to commit suicide over Tahani's work-related trip to Las Vegas.

The station WOIO has obtained a police report dated December 1, 2012, saying that someone had called the authorities saying that Jamal had threatened to take his own life if his daughter failed to return home from a conference in Las Vegas by 7am the next day.
