A detective whose brother has supposedly just committed suicide following the death of his daughter who passed away in a fire along with several other children, is convinced that the death is murder rather than suicide. His basis for thinking this is certainly solid in the sense that several other parents who lost children in the same tragic blaze have taken their own lives but he may just be grieving and not wish to believe that his brother killed himself.
The BAU decide to investigate and quickly realise that the dead parents were all connected in some way to support groups which they attended to help them cope with their loss. All wrote suicide notes in their own hand, and it is deduced that they were not forced to do so. The question is, did they kill themselves or is the young man who keeps turning up at the support groups in some way connected to the deaths of their parents?
This unsub was somewhat creepy, and his methods, very cleverly disguised. (Not from our team at the BAU though!). The saddest part was that the death of the detective's brother really WAS suicide, but even in his grief, his diligence helped to bring a killer to justice.
