Kendra Scott Case is not a Justified k*lling

A Memphis mom has been charged with first degree murder after shooting a 20 year old man dead that she found in her 13 year old daughter's bedroom. Many people online seem to think this is a justified killing under self defense or stand your ground and I'm an attorney and I don't think this is a justified killing and here is why. Kendra Scott out of Memphis, Tennessee arrived home at 1:30 in the morning and immediately suspected a man of being over at her house. The witness on the scene said that her mom immediately pulled up to the house and began screaming, who is in my house? The mom then looked through the house and found the 20 year old, Rodarius Morton hiding under her 13 year old daughter's bed. The witness, the 13 year old daughter, reported that there were some words exchanged between Mr. Morton and Miss Scott and as she was walking out of the front door, Miss Scott shot him in the back of the head. Police found him lying in the front yard. It's important to note that the 13 year old witness stated that her mother had previously stated that if she found another boy in her house, she would shoot him. She knew that if her daughter brought another boy into the house, she would shoot him. Premeditation. Self defense, stand your ground? Absolutely not. We know that self defense to be applicable here, you must be met with some type of lethal force. There are no facts presented here that show Mr. Morton had any deadly weapon on him and he was walking out of the front door and was shot in the back of the head. No, stand your ground is likely not going to work because Kendra Scott did not present any lethal force and she was walking out of the front door. I think that's the only way that Kendra Scott can have a lesser sentence than first degree murder, but unfortunately guys, you cannot take the law into your own hands. You cannot shoot someone in the back of the head as they are leaving your home that they were rightfully invited to by a resident living in your home. This is just my opinion. What do you guys think? Heat of passion? Potentially. Something I think that can pop up during the end of trial is a lesser charge of manslaughter based on the defense of heat of passion. In law school, we learned that a classic example is when the husband comes home and finds his wife and bed with another man and he just snaps and that is manslaughter. But unfortunately guys, you cannot take the law into your own hands. You cannot shoot someone in the back of the head as they are leaving your home that they were rightfully invited to by a resident living in your home. This is just my opinion. What do you guys think?
