The murder of a Bermudian teenager in Britain six years ago is featured in a television documentary.

Lyrico Steede, 17 was stabbed to death in a “honeytrap” killing in Bulwell, near Nottingham, in February 2018, three years after he moved to England with his mother.

His mother spoke of relocating in search of a better life — but underestimating the danger of “street life in the UK”.

Lyrico was set upon by four attackers after being lured to a park by a 15-year-old girl on the promise of a date.

The student managed to stumble to a nearby house for help after the brutal stabbing and was rushed to hospital, but he died from his wounds five days later.

In January 2019, a Nottingham Crown Court jury returned guilty verdicts on five teenagers who had planned and carried out the ambush.

Kasharn Campbell, 19, was sentenced to 20 years and Christian Jameson, 18, was sentenced to 16 years for the murder.

Three other teenagers were jailed for manslaughter.

The Channel 4 programme Murder Case: The Digital Detectives reveals how police were able to track down Lyrico’s killers using groundbreaking digital techniques and social media records.

Detectives used a range of different digital forensic methods as part of their investigation to try and connect the dots and link Lyrico’s killers to the plot.

These included the use of cell site data to map the movements of suspects, downloads and analysis of phone content, and extensive reviews of CCTV footage and automatic numberplate recognition cameras.

The programme includes police bodycam footage that recorded Lyrico’s dying words.

He is heard to say: "I am going to die."

As other officers arrive, the police officer tells them: "He says it happened in this area. He says he was stabbed in the back."

The officer can then be heard twice asking Lyrico: "How many people attacked you?", to which the teenager answers: "Four."

The Pc asks: "Do you know them at all? Do you know why they did it?" He replies: "No." Soon after, a woman officer is heard saying that Lyrico is "semi-conscious". She asks him: "Do we need to let anyone know?" The officer reports: "He shook his head."

Lyrico died from a brain injury caused by a lack of oxygen five days later. He had been stabbed 18 times, including six in the face.

Detective Superintendent Hayley Williams was the senior investigating officer in the case and features prominently in the documentary.

In an interview, she says: “What happened to Lyrico was an absolute tragedy that is still remembered clearly by all of us who were involved in the case.

“More than 100 people worked on this investigation, and it’s fair to say that it was a very complex case that saw our team look through hours and hours of CCTV footage. Over 1,000 exhibits had to be examined to help us decipher exactly what happened and who might be involved, with a number of different techniques used to uncover the truth.

The programme, which aired in Britain on Monday, also features an interview with Lyrico’s mother, Keishaye Steede, who explains the moment she discovered that her son had been stabbed.

Mrs Steede told the interviewer: “There's a knock at the door. It's the police. The first thing they ask me is, where is my son. That's when they say he's been stabbed.

“Everything went out of me. It almost felt like I couldn't breathe. Nothing inside of me believed what he is saying. Lyrico was my only boy.

“People would tell him ‘you're just like your mama’. Our bond was different. That was my baby.

“I moved everyone here for a better life. I wanted them to be able to experience university, college. All of those things.

“Lyrico had gone from my little boy to this big man that was doing his own thing. I think that he felt like he had to be someone he wasn't.

“I was so closed-eyed to everything that happened here in Nottingham until my son passed. He always reassured me that when he was out, he was safe. I didn't know about the street life in the UK.

“I was just thinking about my son, thinking about how he felt when he ran, what did it feel like when the knife went into him, and what sort of thoughts were in his mind.”
