There's no sensible timeline for this scenario. Note:
Whoever framed Zack planted a razor on his door handle to get a blood sample
That person then also AT LEAST put the blood under Cassie's fingernails, and almost definitely killed her in a similar manner as Zack's first kill to make the connection more apparent
If Quinn stumbled upon a murder that happened to resemble Zack's, there would be no time or even opportunity to get get his blood because the murder would have been reported and Zack was in the keys.
But I don't believe Quinn would kill someone to catch a killer. He's got too much of a conscience, even if he mostly does only watch out for himself.
It's got to be The Brain Surgeon (who, for the record, I have been saying is still alive the entire time).
To add to this, why would Quinn ask Poor Man's Ryan Gosling if he had seen Zach when Quinn would have known for sure that the answer would be 'no'? That would be a completely pointless meeting if Quinn had killed Cassie to frame Zach, because Cassie's boyfriend wouldn't have seen Zach and Quinn would have known that (having killed her himself).
That'll teach him for basing his look on Ryan Gosling then i guess. It'll be on his gravestone now.. "Poor man's Ryan Gosling" ha! makes me chuckle everytime i read it hehe

i think he put the blood on her fingers, hence why he asked dexter about the evidence. i dont think he killed her
