Mother, 34, and uncle, 37, will face murder trial over deaths of two teenage sons

A teenager allegedly murdered by his mother went to school with a yellow Mohawk to raise cash for a friend who was dying of cancer, it has been revealed.

Tristan Barrass, 13, appeared on a BBC series called ‘Our School’ in 2017 in which he was filmed in class with his dyed hair.

The youngster, who died alongside his brother Blake Barrass, 14, at a house in the Shiregreen area of Sheffield on Friday, is filmed being quizzed by teachers on his hairstyle.

Tristan, who according to the documentary was known around the school for his distinctive hair styles, tells them: ‘My friend is dying of bone cancer, I asked if I could dye my hair yellow for him. 

His favourite colour is yellow.’

He added that his hair ‘makes me who I want to be. With normal hair, you look like any other person.’ 

In another clip Tristan is seen laughing and joking with school friends in assembly.

Our School is a fly on the wall documentary that follows the everyday lives of the staff and pupils in secondary schools, as pupils move from Year 6 into Year 7. 

The footage has emerged as his mother Sarah Barrass was remanded in custody today accused of murdering her two sons.

She will stand trial later in the year accused of killing Tristan and brother Blake alongside the boy’s uncle Brandon Machin, 37, who is also charged with murder.

Police were called to a property in the wider Shiregreen area of the city at around 7.30am on Friday, and arrested Barrass and Machin. 

Up to 15 police cars, two riot vans and four ambulances descended on the home, while the air ambulance landed at a nearby primary school on Friday morning.

Dozens of floral tributes were left outside the family’s home that was still sealed off behind police tape on Friday.

A steady stream of tearful school children brought flowers, balloons and teddy bears to the scene. An online fundraising drive has been launched to help the surviving children.
