NEW YORK (CBSNewYork/AP) -- A church in lower Manhattan plans to ring its bell in honor of the victims of the Colorado theater shooting.
The Bell of Hope at St. Paul's Chapel will be tolled at 12:30 p.m. Thursday. The bell is a gift from London to New York after the Sept. 11 terror attacks and has been rung following the bombings in London, Madrid, Mumbai and Moscow and the Virginia Tech and the Norway shootings.
St. Paul's Chapel sheltered and fed recovery workers for months during the cleanup of ground zero.
Suspect James Holmes, a former neuroscience graduate student, is accused of killing 12 people in the attack and injuring dozens more during a showing of a new Batman movie at an Aurora, Colo. movie theater.
Meanwhile, investigators in Colorado have been pouring over a chilling package reportedly sent by Holmes to the University of Colorado-Denver/Anschutz Medical Campus where he had been a student.
The letter was sent to one of his former professors, a psychologist at the university, sources said.
In the note, Holmes talked about shooting people and even included crude drawings of a gunman and his victims, sources told CBS News.
The University of Colorado Denver said Wednesday that the U.S. Postal Service delivered the package Monday and it was immediately investigated and turned over to authorities within hours.
A bomb squad robot and x-rays were used to check it for explosives.
The letter may help investigators learn more about Holmes, but experts say not to expect closure.
"I can guarantee you, we will find it unsatisfying because there's nothing that this individual could say to us, the general public, to sit back and say now I understand why you did this," said former FBI senior profiler Mary Ellen O'Toole.
Back at Holmes' apartment complex, work crews are repairing damage to the building that was caused during the investigation. Displaced residents were finally allowed back home Wednesday after the threat of booby traps was cleared.
Holmes will face formal charges on Monday.
