This whole police scenerio is ridiculous. First if she died of a drug overdose, where do the specks of blood come from? Do you bleed out when you o.d.? Losing your bowels and urinating I would understand, but blood? How did they hide the child that quickly and then let it sit for days? I would imagine the odor from a decomposing body would be pretty strong. I for one know I could never ever in a million years be able to function if I were covering up the death of a child, accidental or not. Family member or friend, it would not matter. I would be a complete wreck and not be able to live with it. You are not going to tell me now that there are multiply people involved in this cover-up, all parents themselves and none of them cracked already. How could a persons own DNA not be a 100% match? I read that the DNA was in the 88% range, that to me would most likely be a relative. These detective seem to me to be grasping at straws.
Good point about the blood. Why has the fact that overdosing normally does not involve BLOOD apparently escaped so many commentators? Something doesn’t add up here.
A plausible scenario is this: After their overmedicated child succumbed, the panicked parents decided they could not bear the cost of being held responsible (loss of jobs, criminal penalties, etc.) They decided their only reasonable option was to dispose of the body, but could not immediately because of all the attention paid to them. Some time later they rented the car and disposed of their child with as much dignity as could be afforded under the circumstances.
But all this still does not explain the apparent presence of blood.
You assume ‘bodily fluid’ means urine or feces. Bodily fluid of a dead body could be just about anything, including the liquid that comes from a decomposing (25 days after the fact) body. Sad and sick as that is to type about a three year old little girl.
