The man who shot to death a Virginia Tech police officer on Thursday and then took his own life was a 22-year-old part-time student at nearby Radford University, the Associated Press reports.
The police still have not identified a motive for the actions of Ross Truett Ashley, which threw the Virginia Tech campus into a frenzy of anxiety nearly five years after a shooting spree took 33 lives there.
But the police did report that he stole a sport-utility vehicle at gunpoint on Wednesday and later left it on the Virginia Tech campus. The police also said he did not know the police officer he killed. After shooting the officer, Mr. Ashley ran to a campus greenhouse, where he left a cap, a sweater, and his backpack. He was next spotted in a parking lot, where he committed suicide, the police said.
In a statement posted on its Web site, Radford University said Mr. Ashley was a business-management major from Partlow, Va. The university said the federal student-privacy law known as Ferpa prevented it from releasing any further information about Mr. Ashley.
The police investigation continues, and tonight people on the Virginia Tech campus will gather for a candlelight vigil.
