Daughter Riddles

The mother was the murderer. We know from fact number three that the youngest person wasn't the victim, and from the fourth fact we know the youngest person wasn't the helper and from fact number six the youngest person was not the killer either. Therefore, the youngest person can only have been the witness. If we make up a chart there are now three possible combinations: Oldest person (father) H H M Next to oldest (mother) V M H Next to youngest (son) M V V Youngest (daughter) W W W (H = Helper ; V = Victim ; M = Murderer ; W = Witness) We can work out from fact number five that the father was the oldest and from fact two that the youngest person must have been the daughter. Therefore the next to the youngest must have been the son and the next to the oldest, the mother!

Five - each daughter has the same brother.

The ages are 6, 6 and 1. to solve, you want to write down all the 3 numbers whose product is 36. 1, 1, 36 1, 3, 12 1, 4, 9 1, 2, 18 1, 6, 6 2, 2, 9 2, 3, 6 3, 3, 4 Here's the hardest part, the fact that the doorbell clue was not enough to solve the puzzle means that if we add up each of these options, we get at least two results that are the same, and we need more information to decide which one. These are 13: 1, 6, 6 13: 2, 2, 9 Then to find the last hint, knowing that there IS a youngest child, means the smallest child doesn't have another sibling in the same age, meaning that 2,2,9 doesn't work, and we are left with 1, 6 and 6.

Three. One blonde, one redhead and one brunette.
