you don't find chloral hydrate unless you specifically look for it. Said they only checked ANS after the fact for this drug and since it is such an off the wall drug Wecht and the Bahamian coroners may not have looked for this drug and an exumation of his body to look for this could end up being devestating for Team Stern if it did reveal Daniel actually died from an OD of chloral hydrate ---- note: would explain his sudden sleepiness.
Can you imagine the court battle for an exhumation of Daniel???
