The very first thing which catches the eye in this chart is the placement of planets in Scorpio/ Vṟṣcika (Vrishchika) which governs external genitalia. Scorpio is also the hidden or the concealed and is a malefic sign ruled by Mars and Ketu.
Venus/ Śukra (Shukra), the Kāraka (Karaka) for sex is afflicted in Scorpio and is joined by Mercury/ Budha in the same sign. Mercury in Scorpio in the Navāmśa Cakra (Navamsha Chakra) in trines to the Moon/ Cañdra (Chandra) is a specific combination for excessive sexuality. In the Rāśi Cakra (Rashi Chakra) as well the placement of Mercury in a quadrant to the Moon triggers lewd speech and charges Mercury up with lust. Both Śukra (Shukra) and Budha are planets embodying the Rajas Guṇa (Guna) and are replete with sexual and other desires. The great infection comes from Rāhu/ Rahu, the head, in Scorpio which makes the simmering lust spiral out of control. Vṛṣcika (Vrishchika) has an inherent problem-it is ruled by an Agni Tattwa Graha (fire), being Mars, and is a Jala Tattwa Rāśi (Rashi) (water). This leads to a Tattwa conflict and Scorpio is always boiling with latency and concealment.
Rāhu (Rahu) brings criminality to the lust and exponentially raises the lust of Venus and Mercury. This combination is also imprisoned by the Pāpakartarī Yoga (Papakartari Yoga)(lit.malefic scissors) formed by Śani (Shani)/ Saturn in Libra (Kāma Tṛkoṇa/ Kama Trikona)-sexual behaviour and intercourse and the common man (Śani/ Shani) is exalted in Libra, but could not resist the allure of uninhibited, criminal and violent sexual violation of a woman caused by the unobstructed Argalā/ Argala (intervention) of the planets in Scorpio. Mars and Sun hem the planets in Scorpio from the other side fuelling the rage in the minds of the perpetrators.
The intelligence operating at the time is gauged from the Lagna/ ascendant and its lord. Karkaṭa (Karkata) Lagna/ Cancer rises and its lord the Moon is in the 8th House (symbolic of the natural 8th House of the zodiac-Scorpio) where the Moon is debilitated and in Maraṇa Kāraka Sthāna/ Marana Karaka Sthana (death like suffering). In this case the damaged intellect working at the time has inflicted death like suffering on the woman (Venus). Furthermore, Cañdra (Chandra) is in Aquarius-Kumbha-ruled by Śani and Rāhu Shani and Rahu) .
The Dārapada (Darapada)/ A7 is in the 10th House forming a kind of Jara Yoga and is in the 8th House from the Ārūḍha (Arudha) Lagna in the 3rd Bhāva (Bhava), the apex of the Kāma Tṛkoṇa (Kama Trikona) showing copulation. The 1-8 relationship shows complete deviance in the sexuality manifesting. More importantly, the violent Mars is the lord of the A7 in Meṣa Rāśi (Mesha Rashi), further emboldened by the union with the Sun in the 6th House of crime.
Śani (Shani), the 7th Lord is in the 4th House of vehicles and the 4th House from the Kāraka Śukra (Karaka Shukra) shows the Moon in Maraṇa Kāraka Sthāna (Marana Karaka Sthana) showing the perpetrators already having a 'mind' to commit such a crime (Rāhu lordship of Kumbha).
At least Budha is no longer retrograde and that might help in communications including technical communications. The Criminal Law (Amendment) Bill, 2013 is but a step in this direction and has been passed by a voice vote.
All these measures are occasioned by ghastly episodes which are caused by people with poor Kārmic background which Karma can be triggered by episodes such as this.
