Media response time on April 20th

Odd question but I have been meaning to ask about for a long time.

What is the earliest possible time that the media (e.g reporters, cameramen, photojournalists etc) arrived at the school on April 20th? Like is there a general timestamp like say for example 11:25 AM. I just think it would be interesting if there any photos or videos taken that day were captured or recorded while Eric and Dylan was still roaming the school either pre, during or post-library massacre but pre-suicides. I know there's the CCTV of the cafeteria but I'm more talking about outside the school.

For an odd example for what I'm asking; what wouldve been the time for example this helicopter footage of the school started to record at? Like was it 12:45 PM or 1:20PM?


I know this is an odd question and sorry if what I'm asking makes no sense at all.

According to the CNN timeline, uninterrupted media coverage began around noon and the helicopter went up either shortly before this or shortly after. Around noon, the Channel 7 news helicopter that was flying overhead was asked to land in Clement Park in order to pick up a Sheriff's deputy for an aerial survey of the school.
