A mentally ill man who killed his father by stabbing him 19 times was found guilty of murder by a jury at the Liverpool Crown Court with some of the chilling details of the night emerging during the trial. The court heard that 27-year-old Daniel Renshaw yelled out, "I can't believe I've done this," after repeatedly stabbing his father, Graham, on June 14 this year at their family home in Ellesmere Port, Cheshire.

According to the Daily Mail, Renshaw expressed remorse almost immediately after repeatedly stabbing his father and was heard shouting, "What am I doing? I don't know what I'm doing!" He also reportedly had had a good relationship with his father and later did not remember carrying out the attack.

His brother, Jason Renshaw, was woken up by the sound of screaming and rushed downstairs to see Daniel attacking their father and reportedly managed to grab the knife away and restrain Daniel with little resistance. After the stabbings, Jason had told the authorities that Daniel had suffered from mental health problems in the past and had battled an addiction to alcohol and drugs.

Speaking at the trial about the fateful night, prosecutors told the court, "Jason Renshaw went to bed and to sleep. He was woken by screaming. He soon realized it was his father who was screaming in pain and thought that he was fighting with Daniel downstairs. He ran down to see his father sitting in the living room on a corner sofa with Daniel standing over him. Daniel's back was to Jason."

"He could see Daniel repeatedly striking his father with his right hand," they continued. "Daniel was saying nothing but was making loud aggressive grunts. Jason took hold of his brother to restrain him and then noticed Daniel was holding a knife. He grabbed it from him. Daniel put up no resistance. Pauline Renshaw then rang an ambulance."

The Mail reported that emergency treatment was given to the father at the scene before he was then rushed to the hospital for further treatment. However, his injuries would prove too severe and he would succumb to the grievous wounds just one hour later.

Jason's claim that his brother had mental health issues wasn't too farfetched considering the odd behavior the 27-year-old displayed in the lead up to and the aftermath of the stabbing. One day before the stabbing, Jason says he saw Daniel drinking a can of Strongbow in the kitchen while intensely staring at the wall. Later that same evening, he said he saw his brother rocking on his bed while looking at the floor. A few months prior to that, he was found on the train tracks contemplating suicide because he said he had heard voices that encouraged him to end his life.

Then, when he was taken to the hospital for treatment after the attack, he allegedly was seen "sitting on a couch making noises," later telling medical staff he had cyanide in his system and that he desperately needed oxygen. Then, early next morning, he was seen rocking and screaming "oww" while holding the right side of his torso. Officers who arrested him described him as "shocked or catatonic."

During his trial, the 27-year-old admitted to only manslaughter, claiming his poor mental health meant he had diminished responsibility. However, a jury disagreed, convicting him of murder. He is scheduled to be sentenced on December 18.
