Opal, you posted the 2am chart because you think it possible that the murders took place just when they returned to the house?
That does seem very early, and the authorities put the murders at a later time.
However, it is also true that the Moon at that early time is in the degree of the eclipse, which could have acted as a trigger.
The 4:15 chart on the other hand seems late.
However it reflects the Libra ascendent of the eclipse chart, and places Uranus by the cusp of the 8th house.
Your theory about the drug money is admittedly a rational interpretation of the eclipse chart with the 2nd/8th houses activated.
The eclipse chart has Saturn in 5th exactly square the Sun/Venus midpoint, with Venus being the ascendent ruler. This could refer to a bruised ego, a rebuff and sexual rejection.
