Parkland is Columbine part 2

Columbine and the Parkland School Shootings Have much in common.
Freshman Chris McKenna sees Cruz on a second-floor hallway, loading his rifle. “You’d better get out of here,” Cruz said, according to McKenna. “Things are gonna start getting messy.”
Brooks Brown, who had walked outside for a cigarette, saw Eric Harris and confronted him in the parking lot, telling him he was an idiot for missing an important test that morning. "It doesn't matter anymore", Eric told him. "I like you Brooks. Get out of here."
There were at least THREE Shooters....Possibly More at Columbine.
"I wondered why the SWAT teams weren't there yet. I thought at any time someone would come in and say 'It's all right to come out.' It didn't take that long to get to the school." Sometime after 1:00 p.m. Nielson says she heard someone return to the library and she heard more shots. "I didn't hear any conversation, any yelling, just rat-tat-tat.'' Nielson even checked her watched for the exact time.CNN confirmed Nielson's statement, "One student identified as James, who called a television station on his cell phone from inside the school, said he had heard more shooting around 1 p.m., about two hours after the incident began."

"I knew there was no way that was possible,'' Nielson said in reference to the belief that the gunmen killed themselves at around 12 noon. "When I looked at my watch and saw 1 o'clock, they hadn't come back to the library.'' By 4 p.m. she was finally found by a SWAT team and escorted out. She did not look at the bodies laying in the library as she left."I could see hundreds of backpacks scattered everywhere, and at the door there was this backpack we were told to be careful of.''

An April 20th CNN report confirms part of Nielson's account with the following account from witness Cathy Clark who was in the library, "This girl [Nielson] came up screaming ... like, 'Someone's got a gun.' She said get under the table. So everyone got under the table. These two guys came up and they were shooting randomly -- there was bombing, I guess, downstairs and people were screaming." (Were bombs going off downstairs synchronously while the gunmen were in the library?) - http://www.apfn.org/apfn/Columbine2.htm
