I've read enough charts to realize that there are no single placements that can explain such complex motivations. This is not a timed chart, either. It is a noon chart (local time) but in an effort to keep the zodiac natural, which I suppose is a nod to the fact that no birth time is known, the Sun ends up in what would normally be the 2nd house. Without an ASC and a ruler, it is impossible to be certain about much. But personalities like his are fascinating, so I will mention this:
Based on the chart as shown, and realizing that an actual birth chart could change the Moon sign and make other significant alterations, I note the Mercury, rational mind, is combust, Mercury is also in a wide square to a debilitated Saturn, making his mental processes a little skewed. Venus, ruler of Mercury and the Sun is in an adjacent sign or in aversion to the duo and cannot help. Moon - Jupiter ( if a valid aspect in his actual chart) shows a grandiose imagination, but this does not work with the rational thought processes (Mercury) as it is not in aspect with Mercury even by sign.
Moderns will leap at the Uranus opposite Jupiter aspect, but that aspect was in effect for months in 1948, which means millions have it and they all didn't act like Abagnale.
If you're up for some speculation, try this: If he were born several hours after noon, his Moon could be in a nice trine to Mercury. This would indicate that they would work together well, i.e. his imagination and rational thought processes are in harmony. But the Moon would then be debilitated as is Mercury combust, so they would work together for ill, not good. The Moon would also be disposited by a debilitated Saturn. If I were to attempt a rectification, I'd start with that.
I'd like to see a timed chart for him.
