One possible motive could be psychological illness. Some killers have distorted minds and might target young boys because they see them as vulnerable. They get some sort of sick satisfaction from harming the innocent.
In some cases, it could be for financial gain. For example, if the boy is from a wealthy family, the killer might kidnap and then kill the boy in an attempt to get ransom money, although this is a more complex and pre - meditated form of killing that also involves greed and a lack of moral compass.
Revenge is another motive. Maybe the killer has a grudge against the boy's family or someone related to the boy. So, they take out their anger on the young boy as a way to get back at those they have a problem with.
One possible motive could be money. Maybe she was after an inheritance and decided to eliminate those who stood in her way.
Mental illness is a significant factor that could be a motive in a 'killer granny true story'. An undiagnosed or untreated mental disorder might lead her to act violently. Also, fear could be a motive. If she felt threatened in some way, she might resort to killing. In some cases, a sense of self - righteousness, believing she is doing the right thing by getting rid of someone she deems 'bad', could also be a motive.
One possible motive could be jealousy. If one friend is more successful or popular than the other, it might lead to envy and ultimately murder.
There are several potential motives. It could be due to a mental disorder that made her lose touch with reality and act violently. Or perhaps she felt threatened in some way and thought killing was the only way to protect herself. It's also possible that she was influenced by someone else who pushed her into committing these crimes.
One possible motive could be a desire for control. Serial killers often feel powerless in some aspects of their lives, and killing gives them a sense of power over others.
Self - interest is another motive. Like Susan Smith, who was having an affair and saw her children as an obstacle to her new relationship. She was so focused on her own desires that she committed the unthinkable act of killing her own children for her own self - serving reasons.
In some cases, mental illness can be a factor in a 'killer among friends based true story'. A friend who is suffering from an undiagnosed or untreated mental disorder may have delusions or hallucinations that lead them to believe their friends are a threat or are somehow 'evil'. This could cause them to act out violently. Also, a sense of power and control can be a motive. Some people get a thrill out of having power over others and may see killing their friends as a way to assert that power.
Well, revenge might be a motive. Maybe Ruth Finley did something in the past, unknowingly or not, that offended or hurt someone deeply. And that person, nursing a grudge, decides to take revenge by becoming a killer in the story. Another possible motive could be power. If Ruth Finley stands in the way of someone's quest for power, whether it's in a social, business or other context, that person might be driven to kill her to remove the obstacle.
Jealousy might be a motive. For instance, if she felt that another family member was getting more attention or love, she could have lashed out. Another aspect could be mental illness. If she had an undiagnosed or untreated mental disorder, it could have led to violent behavior.
It could also be related to some past secrets or grudges. Perhaps there was an incident in the past that the friends had forgotten about, but the killer held onto it and let it fester until it led to murder. Say, a childhood incident where the killer felt wronged by the group of friends but never spoke up about it.
