Those who are William Lilly's sticklers may want to read Ken Gillman's analysis of Lilly's indicators of violent death (15):

Both lights in violent signs, not both in the same sign, which do not aspect each other, indicate a violent death.

Both lights with violent fixed stars, within 5?, especially if Asc-ruler and 8th-ruler are also conjunct either of the lights, or if either of the lights is ruler of the Asc or 8th house.

Either the Sun or Moon is in a violent sign and the other is with a violent fixed star and one of the malefics aspects either the Sun, Moon or 8th-ruler.

Both lights conjunct, square or opposite Mars and Saturn, with one of the lights and a malefic in a violent sign or with a violent fixed star.

Both lights afflicted by one malefic and the other malefic impeded or in a violent sign and having dignity in the 8th.

Mars conjunct Saturn in an angle, especially the MC, in a violent sign.

Mars conjunct, square, opposite or MR Saturn in any signs in any house if one of them is "challenging power in the 8th."

A malefic in the 8th and the 8th-ruler afflicted by a malefic from a violent sign, with one or both lights afflicted or in a violent sign.

8th-ruler in Asc in his Fall or Detriment or in a violent sign or with violent fixed stars, and a light afflicted by a malefic.

8th-ruler in his Fall or Detriment afflicted by a malefic, and a light or the other malefic in a violent sign.

Asc-ruler in a violent sign or afflicted by a malefic, and the dispositor of the appropriate light (Sun in diurnal, Moon in nocturnal) also in a violent sign or afflicted.

Asc-ruler is a malefic and is in the 8th afflicted.

Asc-ruler in 8th in a violent sign and square or opposite a malefic.

Asc-ruler or 8th-ruler is dispositor of a light, in detriment or fall, and a malefic afflicting the other light in a violent sign.

Moon in 7th in a sign containing violent fixed stars and square or opposite the Sun, or a malefic is in the 8th or ruling the 8th, and both are in violent signs.

If either Venus or Jupiter is in the Asc and the other in the 8th house ? death will not be sudden or violent.
