SAUL LOEB/Arizona Daily Wildcat \UAPD and TPD block off the main entrance to the Main Library last night, after an e-mail was sent to three media outlets. The e-mail said that a man would go on a shooting spree at the UA library and he would kill aimlessly.

A person who identified himself as Jonathan Doe sent an e-mail to various media outlets around Tucson yesterday evening, saying he was going to kill at least six students and faculty or "anyone else that got in his way" at the UA library at 5:30 p.m., police said.

The threat caused university officials to shut down the Main Library until 7 a.m. this morning.

An investigation was underway to track the e-mail, UAPD Commander Brian Seastone said, which came only two days after a shooting spree at the College of Nursing left four dead.

"(An e-mail) this specific and detailed is very, very rare," Seastone said.

The e-mail, which was sent at 5:09 p.m. under the subject heading, "my shooting spree, news at six, urgent," to the Tucson Citizen, KOLD Channel 13 and KGUN Channel 9, came from copycatkiller520@yahoo.com, Seastone said.

KOLD notified UAPD at 5:17 p.m., and the decision was made to evacuate the library and disperse the crowd, Seastone said.

In the e-mail, the sender said he wanted to break the record, that he had nothing going for him and that he wanted to leave his own legacy, Seastone said. The sender added that he was not going to be a coward and kill himself, and would make the police kill him or make the state kill him with the death penalty.

He ended his e-mail by saying the police had until 5:30 p.m. to e-mail him any questions, and that the police should look for his thesis if he didn't survive.

UAPD called in the Tucson Police Department to assist in clearing the library, in which the police checked for any suspicious packages.

A police helicopter also made a few fly-bys of the library area just after 7 p.m. to look at the rooftops of nearby buildings, Seastone said.

"This individual has disrupted the daily (routine) of the library and has made a serious threat that will be dealt with to whatever extent we are able to do," Seastone said.

At around 7 p.m., a member of the library staff came out and said the library would not reopen until at least 7 a.m. this morning, but that people who left things inside would be able to retrieve them.

Other students who were using the library were not allowed back in.

"I have a video assignment due tomorrow at 9:30," history junior David Mendoza said. "I pretty much had it all done, I just needed to revise it. (But the police) are just taking into consideration the safety of the students. Hopefully I can get an excuse from my professor now."
