There are two pointed questions that he gave an answer to - many questions he stated he did not know the answer to, but these 2 questions were answered with a no:
1. Was anything else missing from the house. NO, and he follows up with, but if there were I'm not sure I could tell you. But his answer is no at that time.
2. He is later asked if there were indications that an intruder had been in the home. He specifically answers NO, other than the window appearing to be tampered with.
I will note that we do know when the 911 call came in, now that I review the press conference, the call came in right around 4. But what was not known at that time was at what time the father got home from work. Young was asked if they knew, because at that time media had heard that the father arrived at 4, and Young said that that "might be", but he didn't have exact times when people came and went.
I understand that Capt. Young wouldn't know everything that was occurring in the investigation, but at the same time, cell phones being missing from the home is not a trivial finding in this case. AND, at that point, would be their number one chance to try to track down the baby. So, if we were talking about keys being gone, that's another issue. When we're talking about 3 cell phones any of which could be vital tools in tracking the abductor and finding the baby...that's a whole nother ball of wax. That Steve Young didn't know that information yet, when asked in two different ways, is disturbing.
