Their
He didn't witness the killing himself but did find his dead mother in the bedroom. He went through things that no kid or person should see in their lives, but who did he cry out to? Also, the stepfather did not take his own life; he died a normal death.
Those kids he killed lost their mother and basically their father that day as well. They ended up being adopted by their aunt after being in foster care for a while.
The family has seen this type of post online and has complained and ask for people to stop painting the killer as "an innocent mentally ill" man. At the end of the day, he did kill his 2 teenage brothers, and what happens to him after this only Allah knows.
