Chang had been teaching at UNLV since 2001, most recently at the Lee Business School. His academic profile shows he had been published in several journals and featured as a speaker at numerous conferences. He was a certified information systems auditor.

Navarro’s teaching focus was in accounting information systems. She was researching cybersecurity disclosures and assurance, internal control weakness disclosure, and data analytics.

A fourth person, only identified as a 38-year-old male visiting professor is still being treated at the hospital for life-threatening injuries.

“On behalf of the office, our deepest condolences to the families of the victims and those impacted by this tragic event,” the coroner’s office said in a statement.

Sources told Nexstar’s KLAS the gunman, identified as Tony Polito, was a longtime business professor who had unsuccessfully sought a job at UNLV. Sheriff Kevin McMahill said investigators are still working to pin down a motive, but the gunman did not appear to be targeting students. McMahill said he entered campus with a list of people he was seeking.
