An upset mother let out her frustrations on a bus driver when she refused to call for help when her daughter got seriously hurt while on her way home from school Monday.

Stephanie Vann, who struggled to fight her tears, poured out her emotions in an interview where she told about the helpless situation of her daughter, Serenity, after she hit her head on the window of her school buss.

According to a source, Serenity was laying on one of the bus' seats when her classmate offered to help her stand. Unfortunately, she lost her hand and Serenity fell backwards, hitting her head.

“I was laying on the floor and a bunch of people were surrounding me,” said Serenity, an 8-year-old student from Aurora Public Schools.

Stephanie, meanwhile was at work when her older daughter, who was also riding a bus on her way home from Arkansas Elementary, called and told her about Serenity's misfortune.

Stephanie found her daughter on the couch when she arrived home after the call.

“She was laying on the couch, convulsing; she was not breathing right. Her eyes were open. She looked dead. Completely dead,” said Serenity's mom.

Vann said the bus driver did nothing to help her daughter. She didn't even call 9-1-1 for medical assistance. Instead, it was 10-year-old Zuart Martinez and two more of Serenity's classmates who helped her inside their house.

“We got her in the house and she was staring and like, she was not doing nothing and her eyes were open,” said Martinez.

Meanwhile, KDVR reported that the bus driver allegedly refused to call 9-1-1 “because of the cost” and just reminded the students to be careful next time.

“The fact that she saw her like that unconscious and left I just have no words... I can't believe she didn't try to help.

“She just left, she just left my kid; she didn't wait to see if I was here or anything,” expressed Stephanie.

In a statement, Aurora Public Schools said that the bus driver called dispatch for help. They are also reviewing whether and how the driver followed protocols.

It also extended the school's well wishes to Serenity and that they are focused on giving her and her family with support.

Serenity was advised that the driver was still employed, but was assigned on a different route. Police are not investigating the case since “nothing criminal took place.”
