Please see my earlier article for preliminary thoughts.
I’ve now found an unverified date of birth for the shooter (September 10, 1988, time and place unknown) from his apparent 2007 criminal record. Loughner has both the Sun and Moon in Virgo but the notable thing in this chart is the challenging T-square involving Neptune, Mars and Chiron all between 6 and 9 degrees of the cardinal signs (Neptune in Capricorn, Chiron in Cancer, and Mars in Aries. That Aries Mars has a powerful drive and motivation, but the square from Chiron suggests problems with the development of a healthy expression of Mars, and the square from Neptune erodes the confidence of Mars and results in one’s anger and rage being driven underground.
All of that complicated drive/anger/rage of Mars doesn’t fit well in the Virgoan personality which tends to prefer life nicely ordered into manageable pieces, and I suspect that there were two sides to this young man’s personality. Then along comes not only the Saturn and Uranus transits that I reviewed in the post earlier today (see link above) but also a transit of Pluto over that Neptune and exploding the Mars T-square like a powderkeg of anger and misguided rage which appears to have been directed against the government but was likely meant for people closer to him, perhaps his parents – perhaps himself.
