A father who repeatedly stabbed his own daughter before being shot down by armed police during a psychotic episode is suing the NHS for over £1m in a unique court case, claiming doctors botched his mental health treatment.

Marc Traylor, 16, used two knives against Kitanna, his daughter. He took her hostage in Hersden (Kent) in February 2015, and was also suffering from psychotic delusions.

Her father’s attack ended with police intervening to shoot him three more times. However, Miss Traylor was left with multiple stab injuries to her right arm. Chest, stomach, and right leg. She also suffered lacerations to her liver, colon, and spleen.

Marc Traylor (47) was killed by specialist guns after stabbing his daughter Kitanna multiple times during a February 2015 siege at their Kent home. He also suffered a psychotic episode.

Kitanna Traylor (pictured) sustained severe injuries in the attack. Her father and she are now suing NHS for failings in their mental health care, which they claim contributed to the attack.

Traylor (47) is now suing Kent and Medway NHS and Social Care Partnership Trust, claiming that Traylor was negligent in changing his anti-psychotic medication and failing to monitor him properly in the community. This led to Traylor’s attack on his daughter.

London’s High Court heard Traylor was taking medication after he had been diagnosed with paranoid schizophrenia. He was delusional that he was poisoned or that others were trying to kill his brain.

Following the kidnapping of his daughter, now 22, in their family home, he started smiling at her with a “devilishly and chilling” manner before telling her to stop. He then flew in a blur, stabbing her.

Later, he was tried at Canterbury Crown Court for attempted murder. However, he was not found guilty of the crime by reason insanity.

Traylor suffered brain injury from gunshot injuries by police, ending the knife attack.

Now, his attorneys claim that he would not have suffered a breakdown or had to attack if he continued on slow-released ‘depot shots’ instead of switching to self-administered tablets.

According to the court, Traylor would have been treated properly and informed while on correct medication. 

He further claims that he shouldn’t have been allowed to be in the community without proper supervision so that events like February 2, 2015, wouldn’t happen. 

Miss Traylor has also filed a lawsuit against the NHS, alleging that the NHS breached her Human Rights Act rights. Staff claimed they failed to prevent the “real and urgent risk to my life” presented by her father. 

Lawyers say their claims in the High Court are valued at over £1 million.

Police surrounded Traylor's house and searched for evidence after he was taken to hospital

Following Traylor’s arrest, officers searched Traylor’s house for evidence.

Bishop, the defence QC, said that Traylor should not be paid cash for any violence he has caused.

According to Mr Bishop, the ‘effective cause’ of Mr Traylor’s loss was his behavior. He noted that Mr Traylor’s decision not to take his medication is a major factor in his loss of control.

According to evidence, Mr. Traylor didn’t take any tablets after receiving his final injection of depot on June 5, 2014. He was suffering from a psychotic episode which led him to the horrific events of February 8, 2015 and he did not consume one tablet.

Bishop continued: ‘Even though Mr Traylor’s defense of insanity excused him of any criminal responsibility, Mr Traylor’s behavior of refusing to take his medication when he was fully capable and aware of its risks – and lying repeatedly about it – constitutes “quasi-criminal”, and should be denied a remedy under legal or policy. 

Traylor had already been taken into hospital and was being treated between December 2012 through June 2013. One year later, Traylor informed his psychiatrist that the injections he received were going to be replaced by oral medication in an effort to avoid further psychosis.

His daughter and Mr Traylor have their lawyers agree with the law that they could not force him to get any more shots as he was found to be mentally competent. But, they claim that it should have been strongly recommended that he continue to receive his depot injections.

Before the psychotic episode which led to the shooting, Traylor was being treated by the Kent and Medway NHS and Social  Care Partnership Trust

Also, Traylor was discharged from secondary mental hospital care’ in December 2014 and community mental health care’ on February 6th 2015 – two days before the horrific attack.  

This is the ongoing case.
