In the live interview with Larry King, Howard K. Sterns admits to taking pictures of Daniel after he died. When asked why he would do such a thing he said that Anna asked him to because she didn't believe he was dead.
That doesn't make too much sense to me... I mean - imagine this.. a hysterical woman who just lost her son screaming, crying, saying she didn't believe her son was dead, then saying - wait take a picture of us.
Weird stuff.
