The sister of Sabina Nessa broke down in tears on Monday's Good Morning Britain as she spoke about her late sibling's murder.
Hosts Richard Madeley and Ranvir Singh invited Jebina Yasmin Islam into the ITV studio to discuss the news that Sabina's killer had been jailed for life.
Koci Selamaj, from Eastbourne, East Sussex, pleaded guilty to murdering the 28-year-old primary school teacher in a sex attack in a park in September last year.
The killer refused to attend sentencing proceedings in court last week, with Mr Justice Sweeney calling this decision "cowardly" - a video link was made available to him, but he turned it down.
He will serve at least 36 years behind bars before being considered for release, but Jebina said she wants him to actually serve life.
Speaking about the huge loss, Jebina explained: "It's all surreal, it feels like a bad dream that we'e all going through.
"It's just heartbreaking, you would never have thought that your young 28-year-old sister was brutally taken away.
"If she was like ill, we could have had some time to spend time with her, make memories. But her life was taken away without a second thought and out of nowhere," Jebina continued.
"It's impacted us a lot, it's impacted myself, my sisters, we're scared to walk the streets alone now, and also given the time of day as well."
Towards the end of the interview, Richard asked Jebina: "Can you tell us, before we finish this, can you tell us what plans your sister had had for her future? What was her life scheduled to be like?"
Clearly overcome with emotion, Jebina apologised before breaking down in tears as Richard quickly said: "Of course, of course, it's quite alright."
Co-Founder of The Sabina Project, Kareema Motala, who was sat beside Jebina, jumped in to answer the question and said: "I think the headteacher said that she had the possibility of becoming a headteacher one day and really implementing and changing the lives of young children."
"She loved teaching?" Richard asked, as Kareema continued: "Definitely, and I think it's really important, I have a five-year-old child and even now I'm trying to teach him the core values. It's important that we get in there and get in there early."
Good Morning Britain airs weekdays at 6am on ITV and ITV Hub.
