FWIW, this is an interesting post by Tuba in the astro thread.
"Not just at Websleuths but in all blogs on this missing person's case, there are questions about why the friends behaved the way they did that night. Under the 9:30 p.m. chart, the first paragraph pertains to the secrecy shown by the intercepts in the Fourth and Tenth Houses. Are these Houses important to your investigation? Very important. Saturn rules the day and the hour and Saturn is found intercepted in H. 4. Saturn rules House 8 and remember, Saturn of this event is exactly square Morgan's own natal Jupiter. Saturn is also quincunx or inconjunct Morgan's own natal Node: her associations, the groups she runs with. So we know there are family secrets, H. 4 and we know the authorities, H. 10, are not laying everything out for public consumption.
The friends, H. 11, appear as rude, inconsiderate and in tension with Morgan but the chart does not expose the friends as withholding information. Now they may be concealing some facts or conversation but it is not apparent in the event horoscope for 8:40 or 9:30.
The car issue is an important one and law enforcement and Dr. Harrington are putting out contradictory information about which car was in the parking lot at the arena. They need to get this sorted last weekend. "
