I've had a couple of thoughts while reading about this heartbreaking loss of a beautiful life.
I agree that MR comes across as self-centered and defensive. I have to keep telling myself that people can come across this way without being murderers. Some people are apparently incapable of expressing emotions like sadness, joy, and disappointment. It doesn't mean they don't feel them though.
It seems to me that MR is "acting" in his latest interviews, mimicking how he thinks he should sound, trying to sound genuinely sad and referring to DR in the present tense, after DR's remains were found. Yet MR talked about DR in the past tense in early interviews and on the DP show. And posters mentioned this in the comments after the videos on Youtube. I personally think that MR reads what people say about him, including here on WS and on the FB pages. Whether or not he's guilty, I think he cares what people think of him.
It's sad to see MR and ER continuing to hurt each other when there's already way more than enough pain to go around.
Also an observation about texting ... has anyone else considered that DR's texts, especially the final ones, could have been sent by someone other than DR? This would open up a new time frame.
