Marcus Ramsay died as a result of a stab wound, after police were called to a ‘large-scale disorder’ outside a house in Horninglow Road, Firth Park at 12.20am on Saturday.
The 35-year-old man who was also a father of two, was taken to hospital with injuries to his upper body but passed away shortly afterwards.
Marcus’ sister Ikeila Ramsay, 39, who lives in Georgia, United States, is calling for justice following her brother’s death, as police lead an investigation into the fatal attack.
The 35-year-old leaves behind his one-year-old daughter and 10-year-old son, alongside his older sister and three bothers.
Ikeila, who’s cousin also died after being stabbed in Birmingham two years ago, is concerned knife crime is getting ‘out of control’.
"We are frustrated, I'm angry as hell, his parents are hurting, siblings are hurting”, she said.
"We are all just devastated and hurt by this because as I said, this should just never have happened to him.
"I most definitely want the person who did this to be caught, I want justice for my brother before other people taking things into their own hands.
"The family just wants the person that did this to be put away for a very long time.”
The 39-year-old who lives in the United States has called on South Yorkshire Police to do more to protect young men like Marcus.
It comes after Sheffield’s new District Commander, Superintendent Una Jennings said ‘attitudes need to change’ in order to combat the rising number of knife attacks in the city.
Police are now urging witnesses to come forward as they lead an investigation into his death.
Marcus’ older sister, Ikeila urged officers to carry out more patrols in areas like Firth Park and provide programmes to educate young people on why they shouldn’t carry a weapon.
She continued: "Something does need to be done about it because it is too much.
"This new generation is different, they take things into their own hands, not knowing the consequences or the outcome of things.
"They want to be cool, thinking that having a knife or killing somebody is OK versus going back to the old school and using your hands if you need to fight.
"It is just devastating, it is just sad.”
Ikeila who will be flying over to England on Sunday to be with her family, explained how Marcus will be remembered.
The 39-year-old added: "He was loved by everyone who knew him, friends, family, everybody.
"He was just a humble guy, he didn't bother anybody and always had a smile on his face.
"He's a nice person, a sweet person, quiet, he was a good dad to his kids.
"He always had his son with him always.
"They liked to travel, play games, he just did normal things that parents do with their kids.
"It is going to be really really hard without him.”
Anyone with any information about the incident should call police on 101, quoting incident number 18 of August 8.
