Sorry but you have posted a spoiler in the thread title that anyone can see and might ruin the book for them. If you can edit the thread title that would be a good idea. I would answer your question but I read the book to long ago to remember that bit. :-)
yes, affirmative. i read this book sooo long ago but i clearly remembered the ending as it made me cry not to mention this is the best picoult book, in my opinion. peter would not be able to live in a prison knowing he is there for the rest of his life. he did commit suicide by stuffing his sock in his mouth.
