Yup, I think he's done this before and also agree it might be reason he left PR.
Regarding my earlier comments - I meant to say that I think it's his brother he talked to on bluetooth those times the postal worker was referring to, when she saw him. Those times he was saying nasty things about her. Brother may be also be doing same job, so they talk. Brother reason he got job fast. I am not sure they were talking at all around the time of the crime though. Also, agree that brother would cover for him if he saw him come back with injuries, whether or not he was involved. Regarding the northborough/westborough incident, I do suspect brother involved and used brother's car, maybe AO didnt have own car yet, too new to USA at time.
I hope they move the trial to my county. They couldn't pull that DNA degraded and therefore resulted in a match somehow BS on me. I work in biochemistry, and I would laugh so hard.
