Are there any confirmed pictures of Adam Lanza's pet hamsters?

I'm aware of one really blurry picture of Adam from the background of a crime scene photo [iirc] where he seems to be holding one of his hamsters, but I'm curious if there are any actual confirmed pictures on the internet of any of his hamsters?

I have pictures of hamsters that I've been told are Adam's but that I don't know the origin or validity of.

Here's the blurry image I mentioned of him holding a hamster:

And here are the images that I'm aware of that I've heard are from Adam:

Any information on these?

This makes me miss the mice I owned as a kid.

I saw a tumblr post talking about his hamsters with those pictures attached and a letter Adam wrote presumably to a teacher about them. This doesn't really help with the validity of those pics though it does state they where taken in 2004
On Sept 2, 2003, an 11 year-old Adam writes a letter to a teacher (I'm assuming) named Mrs. Strait for a school assignment, where he talks about his new pet hamsters:
"I have one hamster in my house, and two at my dad's apartment. The one in my house is a Panda Hamster, so I named it Panda. It is much larger than my last hamster. The other two are Dwarf Hamsters. Dwarf Hamsters are the only hamsters in general that can live together, probably because they are so small. Their names are Chibi and Cheeks."
