There was only one new episode I believe. The one I saw was heart-breaking. A man killed 6 members of his family and tried to kill 3 more, but they survived. Those three were children. Two of the 6 killed were children. They were killed by their father's brother. I looked up this case and he hasn't gone to trial yet. The brother killed was named Cecil Dotson, if you want to check up on the case.
At first the detectives, in Memphis, thought there were multiple killers because there were 2 different guns used, along with a knife and wooden planks. It turned out one man did it all. So on one night, the mother of the killer lost 2 sons, one daughter-in-law, and 3 grandkids. I can't remember who the 3rd adult killed was.
The killer son just got out of prison for murder! Apparently he blamed his brother for being in prison and held a grudge against the family for not doing more for him while he was in prison.
The son who was killed was a gang member, but that wasn't why he was killed. However, the likelihood of getting killed when in a gang is pretty high, I would imagine.
