The admittance of guilt

Due to the fact that immediate family members are always considered suspects in crime cases, Blackwell was needed for questioning. On 8 September 2004, police arrested Blackwell at his girlfriend’s house in Childwall, Liverpool and took him into custody for interrogation.
During police interviews, a sobbing Blackwell admitted killing his parents but said it was “a split second thing” and, “I just couldn’t believe what I’d done”. He told investigators that before his father died, he went over and held his hand and talked to him for a while, telling him he still loved him.
Shocked neighbours described Blackwell as a lovely, quiet and clever young man, who played tennis and studied hard. Not one of them could believe such a tragedy had befallen such a seemingly pleasant and normal family.
