My thoughts:
-"Daddy" is not capitalized, odd
-Proper grammar, except for "I" is......which sounds like a child (purposeful?)
-Underlined words for emphasis (special meaning), on words I, Dad,Pop, She and I am Safe
-Quotations.....a child would not use those
-Is that a smiley face above the Kisses??
-Obviously an attention seeking statement, and very bold, it seems taunting to me. A vicious prank or a way for the perp to re-insert themselves into the case?
I still am thinking this is middle school aged kids... Teeneagers attempting to REALLY put EMPHASIS on certain points of this little note, all the
OVERLY using of punctuation and underlining to get their point across tho, I will admit I originally thought "boys" at first, before even reading it, but now looking at it above in wondergirls upclose&detailed version of the pic I am still convinced older kids/teens but instead of "boys", I am almost certain it is "girls"..
I know, I know to some that still have an old fashioned(and that in no way is meant derogatory rather just thoughts of the way things used to be. As IMO the world seems to get more and more evil by the decade. so wanted to emphasize that "old fashioned" was in no way meant in a derogatory way

) way of thinking may not agree that young girls would do such, but let me say I have a middle school age son and there are alot of girls capable of alot more than just writing crude crap on banners.JMO
I'll point out the things that make me quite certain that its a teenaged
GIRL..
First as I stated above the OVER use of punctuation and underlining to make sure EVERYONE see
THE EMPHASIS ON THE IMPORTANT WORDS THEY WANT NOTICED... This IMO screams dramatic teenaged girl..
Secondly, signed with the "
KISSES". This is a female "sign off", just not gonna be used by a male.
And last, and to me this is the dead give away signature of a girl. The "symbol" above the "
KISSES" is a smile, with cheeks on each side(the parenthesis pointed outward on each side represent cheeks with the smile in the middle) ... )~( ... <--Thats the best I can do to represent it with keyboard symbols but I know everyone already knows exactly what I am talking about(and I'm presuming someone upthread has long ago already stated what the symbol was) but I am just saying this to me is a dead give away of a teenaged girl..
I have in past couple of years confiscated, come across, and even snooped thru my fair share of teen notes and this is IDENTICAL type of WORDING, PUNCTUATING, SIGNING, AND USE OF CUTESY-CUTESY SYMBOLS that is seen here crudely&rudely scrawled across Kyron's precious banners!! JMO
