Nah. This is a scam. If "your" cousin was killed, you complain to another cousin, who complains to his cousin and that complains to me. If you just put a poster on a fence, it means "you" are either a scammer trying to play my feelings (a.k.a. animal instincts) for some selfish gain, or you are a person:

1. Who is very unlucky, forgotten by god, due to bad karma from the earlier life is unjustly undeservingly lonely, thus have nobody you trust or nobody that trusts you to complain to.

2. Who is deservingly and justly lonely.

In both cases nobody will change the world to help your exceptional case.
