In layman's terms, what would've happened forensically if a person had deposited fresh semen at the locus, on Jodi's t-shirt or body? Given the way the crime scene was managed (i.e., the clothes & body being left uncovered for a full 8 hours, exposed to the open elements and periodic rainfall), would it have severely degraded the semen to the extent that it wouldn't have been able to be detected at all? I presume rainfall would degrade the semen to some extent, but not to the extent that no profile could be obtained, partial or otherwise?
Incidentally, I don't think the semen on the t-shirt was transferred from another item of clothing during a washing machine cycle; rather, I think it was transferred onto the t-shirt directly by SK (SK and Janine were in an intimate sexual relationship) and it survived the washing cycle. Jodi borrowed the laundered semen-stained t-shirt (she was obviously oblivious to the fact it was semen-stained) and the rainwater spread more of the semen to other clothing (her bra, for example) and parts of her upper torso as it lay there uncovered for hours. Likewise, LM's partial profiles could easily have gotten there innocently as he was in an intimate relationship with Jodi (this explains why his partial profiles from semen were present on Jodi's bra and body).Who's to say that Jodi wasn't wearing a laundered bra with LM's semen still embedded in it (it's well known that LM had sex with Jodi on Saturday 28.06.03)? Like I said, they were in an intimate relationship and having sex regularly. So many hypotheses and variables to consider. And there's the fact that her clothes were all bundled together in one big heap as opposed to the items of clothing being bagged separately. But, as I said, SK had a solid alibi for that evening (well, between 1600-2030 that evening) from his father and Janine herself (both Janine and SK were at SK's father's house for dinner netween 1600 - 2030 on 30.06.03). It's absurd that certain people think it's possible that Janine had anything to do with it.
Btw, what size was the semen stain where SK's full profile was obtained?
