The body of Edgar is there, laying on the floor of Knitty Kitty Club. Police officer Fuzzball won't let you touch the body before it has been photographed.
Talk to Fuzzball about examining the body until you unlock the Police HQ. You should find a photographer from there.
I think you need Edna's help to find a photographer. When you use the interview door she will talk to you.
Don't you want to know what she is doing? ?
You just need to get her out of the interview room.
Use the interview door, again
And all the photographers are out! What a luck. There has to be another way to lure Fuzzball out.
Krakowski is the answer here. If you would get Krakowski in trouble, his buddy, Fuzzball, would surely help.
Did you notice the Krakowski poster on the Police HQ notice board?
So, you fed a peanut to him? Go tell Fuzzball about the code 7.
You can now examine the body of Edgar.
