An Oklahoma man was fatally shot Friday evening by his neighbor who had a criminal history with the family and allegedly called them 'dirty Arabs', police say.

Khalid Jabara, 37, died Friday night at a hospital after being shot outside his home in Tulsa reportedly by his 61-year-old neighbor, Vernon Majors.

Police say Majors, who has a criminal history with the Jabara family, left the scene after pointing a gun at a witness.

He was found hiding behind a tree at Hardesty Regional Library and was transported to a hospital instead of the police station because he became ill, KJRH reported.

Majors was awaiting trial for aggravated assault involving Haifa Jabara, the mother of the shooting victim.

Last year, Haifa was jogging through the quiet neighborhood when she was almost killed in a horrific hit-and-run.

Authorities arrested Majors, who confessed to the crime and even offered police a motive, calling the family 'filthy Lebanese.'

He bonded out of jail on May 25 and returned back to his home, right next door to the Jabara family.

Khalid, who ran the family catering business with his mother, had learned on Friday that Majors was armed with a gun.

'Khalid called the police stating this man had a gun and that he was scared for what might happen,' his sister, Victoria Jabara Williams, wrote on Facebook.

'The police came and told him there was nothing to be done.'

Moments later, he stepped outside to retrieve the mail while he was on the phone with his family when he was shot and killed.

Once Majors is released from the hospital later this week, he will be formally charged with first-degree murder, police said.

'This certainly is a tragedy… but this is not a whodunit,' Tulsa Police Sgt. Dave Walker told The Washington Post.

In the heartbreaking post on Facebook, Victoria said that her family, who are Christians, lived in fear of Majors.

'My family lived in fear of this man and his hatred for years,' she wrote.

'Yet in May, not even one year after he ran over our mother and despite our repeated protests, he was released from jail with no conditions on his bond — no ankle monitor, no drug/alcohol testing, nothing.'

'This man was a known danger,' she continued. 'Our brother's death could have been prevented.'

According to the Post, prior to moving to Tulsa, Majors had a history of violence.

He was convicted in 2012 of making 'criminal threats' and assault with a deadly weapon in San Bernardino County in California.

Majors moved shortly after to Tulsa, where the problems started with his neighbors soon after.

Haifa filed a restraining order against Majors on August 6, 2013.

She claimed in the complaint that he 'harassed' and 'stalked' her by 'knocking at windows late at nite (sic), harassing me with ugly sex words over the phone, taking pictures and harassing my helper in garage.

'He is very racist towards foreigners and blacks.'

On March 18, 2015, police arrested Majors and charged him with violating the restraining order.

'F— you and I want to kill you,' Majors told Haifa, according to a police report.

'Jabara also stated to officers that Majors said multiple racial slurs to her today in her driveway.'

Over the summer, the tensions between the family and Majors increased, as he continued to allegedly threaten the Jabaras.

'He repeatedly attacked our ethnicity and perceived religion, making racist comments,' Victoria wrote on Facebook.

'He often called us "dirty Arabs", "filthy Lebanese", "Aye-rabs", and "Mooslems".'

She ended the post, by paying tribute to her late brother.

'At the end of the day, my beautiful brother had a heart like no other,' she wrote. 'Sensitive to the core, he loved others so much and wanted to be loved back.

'I'll miss his jokes (I stole all my jokes from him!), his love for all things electronic, his love for my mom and dad, Rami, and his tenderness towards his nieces.

'This angel will be missed. Love you, Khalid.'
