It is a very convoluted case. I don't know why the WMPD expected to close it within a month, I don't think the FBI would have solved it in that time frame, and they have much more experience than the police in West Memphis.
Just to confuse things further - the other Jason Baldwin is, (or was), a friend of Robert Burch. The rumor mill in West Memphis at the time had several different strands going - one around Damien Echols and one around Robert Burch, and another around both together! Which Jason Baldwin features in which rumor is really anybody's guess, and the West Memphis police never made any attempt to ascertain which one Jessie Misskelley was talking about.
