UNLV shooting: Ex-professor had 'target list' when he killed three on campus

An ex-college professor was "struggling financially" and carrying a "target list" when he fatally shot three faculty members and injured a fourth at a Las Vegas campus, say police.

The 67-year-old suspect was fatally shot by police during Wednesday's attack at the University of Nevada.

Officials said being denied "several" jobs at various colleges may have been a motive for the shooting.

He also posted a white powder to at least one university before the attack.

Two of the victims have been officially named as professors Cha Jan Chang, 64, and Patricia Navarro-Velez, 39. The name of the third victim would be released after relatives had been notified of the death, said college officials.

The fourth victim, a 38-year-old visiting professor, was in a critical condition in hospital.

The gunman, Anthony Polito, was carrying a legally purchased 9mm pistol and 11 magazines, police say, adding that they are still trying to determine how many shots were fired.

The BBC's US partner CBS News reports that Polito, a former business professor who had taught in Georgia and North Carolina, had applied for a position at the UNLV, but did not get the job.
