I think the murder was on purpose and that Lisa and Ralph acted together. The reason I think Lisa and Ralph acted together was because of Ralph's sperm in Lisa, and their intercourse was not as close to the crime as Lisa and Ralph's statements say it was. From Lisa's SAK, the presence of sperm was a weak positive, suggesting the last intercourse was a few days ago, and the Y-STR identified the sperm as Ralph's. In addition, the window in the bedroom was broken from the inside, not the outside of the house, which is why we believe that this was not the suspect's entrance, as in Lisa and Ralph's statements. If the window was not broken to enter the house, the suspect, Ralph, would have had to enter through one of the doors to the house, yet none of the doors were broken.
