The proper coordinates for Praia da Luz, Portugal are 8W44, 37N05
I think the hardest thing with an event chart is to determine the significators.
Notice the asteroid Madeline is in the 7th intercepted at the time she was discovered missing. Jupiter rules the hour and is well placed, but also intercepted. That would represent her 10th house parent being held up.
Madeline=Mer/Plu, Plu/POF, Mars/Ne
21Cardinal are the 8th harmonic midpoints. Here we have:
Madeline=Mean BML, Moon/MC, Sun/Plu, MC/ASC, Mo/Node, Ve/Sa
Not the best of planetary pictures. There is confusion, hidden activities and every planet is touched by the asteroid except Jupiter and Mercury with hard aspects.
With the 7th being the person on the defense, the receiving side of the chart, with the asteroid bearing her name in this house, I have to assign the descendant to Madeline. She is the descendant of the ones looking for her.
Venus in mutual reception with Mercury, dispositing Madeline puts Venus in authority over Madeline, ruling the 7th/Madeline, and also the the 5th, someone she loves.
When she was discovered missing she was toward the west of where she started. Her declination is 21N18. The closest are Asc and Ju being contraparallel within a degree or so. She is moving out of bounds as we speak. Madeline was recently conjunct her node at 6'Gem22 so I would say she had just gotten to where she was going when it was discovered she was missing. Or, she had been to this location day before. The node is moving direct and moves 17'/day and moving toward the south. If she left a trail, she may have been seen in public between the 6th and 12th since the S node was within 1* orb of 0Cap during that time. Madeline moves 30'/day, close to the same speed as Venus ruling the 7th. Again, I see Venus and Mercury as significators, along with Jupiter. Madeline's south node, where she came from is 1Cap56 just inside the 2nd cusp in the East-Southeast. The south node is moving Rx back toward the east. It conjoined Pluto on May 12. If I am reading the directions right on the picture of the resort with its orientation to the ocean,
here: the main road into this resort is that direction from the apartment. I'm wondering if I need to look at the directions reversed since she is the 7th. If so then she was taken toward the north rather than south. Did she come from England? That is Northeast of there so I don't think the directions should be reversed. S.node shows where she comes from.
Since the 2nd cusp is the 8th of the 7th and the s.node met Pluto 9 days later, I think she died. The nodes could represent the union with and release of spirit or coming into and separation from body and 9 is a number of culmination. I don't know how many of the asteroid nodes move in opposite directions, but to me this looks like she moved into her future as the north node conjoined the asteroid Madeline, then she released her spirit when the south node conjoined Pluto. A psychic once told me she sees the spirit leave often, a week or so before death. Could the mutual reception with Venus mean it was her mom's time but she traded places? Orpheus, also symbolizing death and grieving, was 6Gem51 conjunct Madeline.
Sadly, Jupiter also represents her parent of the 4th and the Mutual reception puts Venus just as easily ruling the 10th as Mercury which make it likely they would be suspected or blamed for leaving her alone. Venus also rules the 12th of the 7th, Madeline's selfless service and/or her hidden enemy.
The point of death is 2Cancer, opposite the south node of Madeline. 2Cancer is the solstice point of 28Sag, Pluto, being contra-antiscion. Being in water may show where she is burried. I would say a small body of water with lots of rocks or cement around, toward the west, S-west moving Southward before getting to the destination. Looking at Scorpio ruling both 12 and 1, and the fact that Mean Lilith is close by at 21Libra (often being blamed for such things, and being disposited by Venus) I wonder if this could represent the Dead/Red Sea being toward the east of where she was taken. Lilith dwelled there. That is toward the east though. If so, then Pisces representing the ocean toward the North would be the Meditteranean. Lilith is sesquisquare Madeline. It is said that her children were taken so she took other's. She represents where the Moon is furthest away from her children and Moon was also out of bounds at the time. This is an indicator of times of crisis and catastrophe. Venus is also out of bounds, even further.
The asteroid Roberta (sorry, no Robert) was at 28Cancer0, declination 19N40, n.node 7leo21, snode 20Pis38, both moving direct. Since their declination is 2* apart and his is moving south, I don't think he is the one, even though his south node is close to where Mars is and he's trine Moon. Did he come from a Pisces place? Moon trine Mars was the last major aspect to inner planet but Neptune was square after that. Neptune rules Pisces though. I think I read he's from England which is North of there, surrounded by ocean so maybe. It was after his south node conjoined Mars that he became a suspect but the asteroid and Mars were 8 degrees separated when she disappeared and it isn't in aspect to either Madeline, the 7th, Mer or Ve. His n.node on the 9th cusp with him being in the 8th shows trying to help with the investigation by interpreting foreign language. He was square Lilith 7 degrees earlier, but that's quite a bit. He is inconjunct Pluto, an 8th house type, one point against him. Venus is 3 degrees from semisextile Roberta, is that enough? I see the true Lilith is 28Libra28, 20' to exact 12th house type semisextile to Moon, and close exact square to Roberta. Maybe he is involved but this could also explain his interest in wanting to help, being estranged from his daughter. It is is him, Orpheus' north node is just reaching him now and it will sink in, what he has done.
I don't see any indication that this beautiful little girl is still alive. Other things I've seen happen during the void Moon remain a mystery so it is quite possible we will never know what happened to her. I hope we do though because this could help us learn how to solves the mysteries of the void.
