'I killed someone, call me back in 10 minutes', road rage killer's message to mom
Lynda also revealed that Matthew suffered from paranoid schizophrenia and was autistic but he has stopped taking his medicines.

Findon, West Sussex: A man accused of stabbing an elderly to death in a road rage incident has been arrested on the charges of manslaughter.
According to a report in the Mirror, the accused, identified as Matthew Daley, stabbed Don Lock 39 times after the latter had bumped into his car. The incident took place last July in Findon, a village near West Sussex in England.
After stabbing Lock to death, Matthew fled the spot. He pleaded guilty of stabbing Lock but had denied murder count. Matthew said that he had stabbed Lock in a fit of rage, but did not murder him.
The accused has also been charged for attempting to change the number plate of his vehicle. During investigation, authorities also found that Matthew had a history of mental illnesses, which might have been one of the reasons for the crime.
A report also said that after stabbing Lock, Matthew had called up his mother, Lynda, and told her, "I have killed someone." She said that Matthew had called her up and told her "I killed someone", before adding: "I want you to think about what I just said and ring me back in 10 minutes."
While the case was being heard in a court in England, Lynda said she feared that her son, Matthew, might have been involved in the murder case of Lock.
“Matthew often thought people were talking about him and saying horrible things. Especially from the nearby working men’s club. He would call the police, who would sit him down and explain they would have to charge him with wasting their time if he didn’t stop,” Lynda was quoted as saying.
Lynda also revealed that Matthew suffered from paranoid schizophrenia and was autistic but he has stopped taking his medicines. The trial of the case is being heard in Lewes crown court.
