Rowan Thompson, 17, was visiting his mother, Joanna Thompson, 50, for the weekend when he attacked her. After their usual morning jog, the teen stabbed his mother over 100 times. Then, he called 999 and told them to bring a body bag.

Thompson was a private school student with a history of mental illnesses. The crime that took place in 2019 was supposed to go on trial this year. Four days before the trial in October 2020, he was found dead in the mental facility where he was being held.

Reports reveal an inquest into his death will be held in 2021 in Greater Manchester.

Chilling confession

The teen first strangled his mom Joanna Thompson, 50, in their old-fashioned Hampshire village home.

He took a 15 minutes break, and then he started the stabbing. He didn't stop until he stabbed his mother 38 times in the forehead, 64 times in the neck, and 16 times in an arm, Winchester coroner's court was told.

After the killing he called UK's equivalent of 911, 999, and stated:

"I've just killed my mum . . . I strangled her and I've been stabbing her with various knives and whatnot."

At the hearing in July, the operator said the boy sounded "calm, unemotional and quite ordinary manner." Then killer teen continued:

"I need someone to arrest me, as that's what you do, and an ambulance would be nice."

"Bring a body bag or whatever you do."

Furthermore, Thompson told the operator about details of his weekend. He added he'd "had a meal and went to the cinema with my best friends, which was really nice."

Gender identity and mental health problems

According to his father, Marc Thompson, the teenager took his own life, this wasn't the first time he tried to do so.

The dad stated that his son was struggling with "gender identity issues" and had a history of mental health problems, including an earlier suicide attempt.

Yet, psychiatrist John Sandford told the court that aside from minor autism, "there was nothing to suggest [Thompson] was suffering from abnormal mental functioning" when he viciously killed his mother.

Coroner Jason Pegg stated a verdict of unlawful killing for the mother's death, saying:

"No one will ever know why Thompson killed her."

"The only person who knows is Rowan, and he's going to be unable to tell us."

Before his death, the teenager claimed he couldn't remember anything, but he did say he felt strange that morning.

Rowan lived with his father, a magician, as he found his mother to be "controlling and overbearing." But, since they're both gone now, we'll never know whether the fight escalated or the boy had some psychotic episode.
