Something that caught my eye about the DNA evidence today was that there were many small stains found on the clothes the police suspect that Dennis was wearing. The jacket we know yielded Richard's DNA and had small blood stains on it, and it is likely that Richard's DNA comes from the blood. However, a number of other items they think Dennis wore had stains, but didn't yield DNA and tested negative for blood. I thought that meant it couldn't be blood, but Joy Kearnsey says:

If negative hemochromogen test for blood, can't say it's blood? Say presence of blood is not confirmed, says Kearsey

"We can't call it blood, but we also can't say it's not blood. We can't really say one way or the other," she adds
I think it's possible there were more small spatters of blood on Dennis' clothes that were thoroughly washed and so are impossible to tell what they were.
Here's where the other clothing is mentioned:

Now talking about pants seized from Dennis' closet. Visual stains. Inside right front pocket - partial DNA typing profile matched Dennis

@BJMCBC
Inside left front pocket. Same. Inside right front pocket, not enough genetic material. Inside left front pocket, partial, matches Dennis
