If you've already binge-watched The Ted Bundy Tapes and cried your way through When They See Us then you're probably ready for your next true crime hit.
And if you haven't watched I Am A Killer yet, then this one's for you.
Advert
The series follows death row inmates convicted of capital murder, who give chilling first-hand accounts of their crimes.
The first series gained a cult following after it was repeated on Netflix, and now the second season of the true crime show is finally debuting on the Crime+Investigation channel - and Charles Armentrout's story might be one of the most harrowing.
Charles - or Billy, as he was known - ended up behind bars for attempting to murder his father and successfully killing his grandmother, Inez Notter.

He moved to live with his father from the age of 18 after more than a decade of living with his mother and emotionally abusive stepfather. However, his fresh start wasn't quite what he was planning, as when he fell in with a rough crowd things started to go downhill.
Billy got into drugs, and ended up stealing money from his father to fund his habit, even cashing cheques in his name.
But when he got caught, he panicked at the prospect of being sent back to live with his mother and abusive stepfather and things turned sinister.
Fuelled by drugs, Billy fired nine bullets at his father at close range. While he incredibly survived the ambush, Billy was then destined for a life behind bars.

After the incident, he was found guilty of attempted murder and several gas station robberies and sentenced to 28 years. He only ended up serving ten.
But when he got out of jail, things went from bad to worse, as his 81 year old grandmother welcomed him into her home, clothed him, fed him and gave him keys to her car.
Like he did with his father, he regularly stole money. And as if history was repeating itself, things turned ugly when his grandmother eventually called him out.
Beating her with a baseball bat until she was unconscious and then stealing her money, Billy then decided the only thing he could do was kill her. After hitting her ten more times with the bat, kicking and stomping on her, eventually, he succeeded.

Even after she died, Charles carried on forging cheques and stealing her money until his crimes eventually caught up with him.
The killer was originally sentenced to death, but this was later changed to life in prison
He now claims to be remorseful for his actions, adding that he is a reformed character, and has even got married from behind bars.
But should he spend the rest of his life behind bars?

The new programme will look in greater detail at his drug addiction, repentance and self hate, and feature interview from a close friend of his as well as his step-mother and step-sister.
This sounds absolutely gripping.
Charles Armentrout's I Am A Killer episode will arrive December 3rd at 8pm on Crime+Investigation channel. Find this on Sky 156, Virgin 275, BT 328 and TalkTalk 328.
