Was my 300E a drug trafficking car?!

[JordaanDMC-12]

Well I took the back seats off because they just weren't fitting right, they were really loose and I though I would just take them off and put them back on right. I found the typical dirt, wrappers, ect but I noticed under the black insulation sheet a body panel it seemed like was loose. So I took the insulation sheet off and I find the back has been cut... I was like "wow... really?" so I go get my dad and show him and the first thing he says is it was probably used for drug trafficking.. I don't want to believe that but the past owners were pretty ghetto and we live a couple hours way form the Mexican border. I don't really see any other reason to make a cut and hole right behind the gas tank and seat.

Regardless of weather it was or not, how do I go about patching this up? Dear lord I am so glad we rescued this car... It was like one of those abused animals you see on those ASPCA commercials before we bought it.

I did a carfax on it and it has a clean history. So wtf! lol
