An American detainee was convicted on Tuesday of murder and committing a hate crime for killing his Lebanese neighbor in 2016. Stanley Vernon Majors, 63, was convicted earlier this month of gunning down 37-year-old Khalid Jabara outside of his Tulsa home in August 2016. The murder charge carried a life sentence, and the jury recommended that Majors never get the chance to go free — a recommendation the judge followed Tuesday. According to prosecutors, Majors killed Jabara after bombarding him with racial insults in a feud with Jabaras family that lasted several years. It escalated to the point where the victims mother, Haifa Jabara, obtained a protective order in 2013 that required Majors to stay 300 yards (275 meters) away and prohibited him from possessing any firearms until 2018. But prosecutors said Majors was undeterred, and that he struck Haifa Jabara with his car in 2015 and drove off. She suffered a broken shoulder, among other injuries. Officers who stopped him later reported that he was intoxicated. The jury foreman, Randall Hardee, told The Tulsa World that the jury agreed that Majors was having mental problems, but that he also understood the consequences of his actions. Jurors also found it difficult to ignore that Majors had antagonized the Jabara family for years, he said. "I dont know how somebody could treat a whole other family like that," Hardee said. "At the end of the day, I thought Mr. Majors was just an incredibly unhappy man who just wanted to take it out on the world." Authorities said Majors shot Khalid Jabara on his own front porch while out on bond. The Jabara family did not attend Tuesdays hearing and instead submitted a letter to District Judge Sharon Holmes. "We do not believe this defendant is worthy of any more attention," the letter said. Defense attorneys argued that Majors showed signs of dementia and appeared to have problems with his long-term memory, and that these conditions interfered with their ability to prepare a defense. In addition to his convictions in Oklahoma, Majors has a 2009 felony conviction in California for threatening a crime with intent to terrorize. Jabara had immigrated to the United States decades ago to escape the 1975-90 civil war that was raging in his country.
