Missouri teen Kaylee Gain is 'fighting hard to stay alive' say loved ones as her GoFundMe soars to $200,000 after 15-year-old suffered severe brain-damage when her head was smashed against concrete during high school fight

The 15-year-old Missouri girl who was brutally beaten by another teen is 'fighting hard to stay alive' after suffering brain damage in the horrific attack.

Kaylee Gain suffered a skull fracture and frontal lobe damage when her head was repeatedly smashed into the ground during a brawl near her St. Louis high school last Friday. She was left alone on the ground to convulse before EMTs arrived.

The family say Gain has 'major brain bleeding and swelling' and is in 'critical condition'. They will not know the full extent of the damage until she wakes up.

'Kaylee is fighting hard to stay alive and heal but this is only the beginning of a very uphill battle for Kaylee and her family,' her loved ones shared on a crowdfunding page, adding: 'the path to recovery will be extremely hard on the family, not only mentally but financially.'

A GoFundMe created in support of Gain has raised nearly $200,000 in just two days. The fundraiser states that all donations will be use towards 'easing these stressful days, allowing Kaylee's family to be able to be there 100% for her day and night and help with the medical bills that they foresee.'

The altercation broke out at about 2.30 pm Friday near the school.

Video of the incident circulated on social media showing another girl bashing the teen's head into the concrete after throwing multiple punches and sending her careening to the ground.

Gain appeared to begin to have a seizure as groups of other teens brawled just feet away.

Police found the girl suffering from a serious head injury near the intersection of Norgate Drive and Claudine Drive, roughly a five-minute walk from the high school campus. She was taken to the hospital and remains in critical condition.

'In minutes, this family's life shattered when their only daughter was assaulted outside of a North County high school,' the crowdfunding page states. 

'She was left alone on the ground to convulse before EMTs arrived on the scene. She was admitted to one of the local hospitals in Saint Louis with a skull fracture and frontal lobe damage.'

A statement attributed to her parents, and published on a second GoFundMe page, said: 'We are so grateful for the amazing medical staff who have been working tirelessly to give her the best possible chance at a full recovery. 

'We know she has a very long road ahead of her but we remain hopeful. We are so overwhelmed by all the support and love.'

The teen's grandparents confirmed to KSDK that both crowdfunding pages are legitimate and will be used used to 'help with costs incurred from Gain's injuries and the parents' lost wages'.

A 15-year-old girl was arrested Saturday and charged with assault. She was taken to the St. Louis County Family Court and remained in custody as of Sunday afternoon.

Attorney General Andrew Bailey has called on the 'evil' 15-year-old girl who beat Gain's head into the concrete to be 'tried as an adult'.

Bailey announced on X: 'This evil and complete disregard for human life has no place in Missouri, or anywhere. I am praying for the victim.

'The criminal should be charged and tried as an adult. If the victim dies, that offense should rise to a homicide.'

John O'Sullivan, Director of Communications with St. Louis County Courts, told KSDK it is too soon to determine if the suspect will be tried as an adult.

He says a court hearing is expected to be held in the next few weeks.

The Hazelwood School District issued a statement denouncing bullying and fighting within the community

After news of the altercation broke, the Hazelwood School District released a statement condemning violence within the community.

'It is a tragedy anytime children are hurt,' the statement read. 'Bullying and fighting in the community is an issue for which we all need to take ownership and work towards a resolution for the sake of our children.

'The Hazelwood School District offers our sincerest condolences to everyone involved and will offer additional emotional support from our support and crisis team to those in need.'

The statement urged community members to respect the families of those involved and 'pledge to help work toward the betterment of our entire community.'

The district recently came under fire for disenrolling more than three dozen middle schoolers in late February and early March.

The school district's public relations director, Jordyn Elston, told STLPR that the students were ejected because of 'expired residency information.'

Of the 40 students who received letters informing them of the district's decision, thirty-eight were re-enrolled within a week after providing updated information, the district said.

The St. Louis County Police Department is investigating the incident.
