There are chilling new details about the student who went on a rampage at Virginia Tech University and killed 32 people.
Police say, Cho Seung Hui had apparently stalked at least two female students in 2005 and had been sent to a mental facility.
Virginia Tech police questioned Cho Seung Hui several times in November and December of 2005.
After professors and at least two female students told officers they were worried about their safety and his "annoying" behavior.
Wendell Flinchum, Campus Police Chief said, "She made a complaint to the Virginia Tech Police and asked that Cho have no further contact with her."
During that time, an acquaintance also told police they were worried Cho was depressed and might commit suicide.
The string of events led to an evaluation by psychologists.
Flinchum also said, “A temporary detention order was obtained and Cho was taken to a mental health facility."
He was released and returned to campus.
University officials were given no information about the detention because of confidentiality laws.
Now investigators are left to gather evidence and look for answers in this baffling case.
There is a heavy police presence on the campus as this community continues it is struggle to cope with everything that has happened here.
"It is definitely going to take a lot of time and a lot of grieving," said Victoria Athey, VA Tech student.
As survivors remember and honor all of those gunned down in the rampage, classes at Virginia Tech have been suspended until at least Monday and many students have left the area to seek comfort from family and friends at home.
"I want to see my parents, so many people didn't get to see their parents," said Lauren Moscater VA Tech student.
For others it is important to be here and be together.
Jennifer Micieli VA Tech student said, “I have not wanted to be alone this whole time because we are all in shock."
So many are now leaning on a faith, that has been so severely tested over the last two days.
