CLEVELAND - A man accused of opening fire at the Case Western Reserve University business school was charged Monday with killing a graduate student and trying to kill two other people.

Biswanath Halder, 62, was to be arraigned today in Cleveland Municipal Court on charges of aggravated murder and attempted aggravated murder, police spokeswoman Nancy Dominik said.

A gunman opened fire inside Case Western Reserve University's Peter B. Lewis Building on Friday, killing Norman Wallace, 30, of Youngstown. Nearly 100 people were trapped inside the building during the seven-hour standoff.

According to court documents, Halder searched for a job without success after receiving a master's degree in business administration from Case in 1999. The native of Calcutta, India, had aspirations of running a business.
