In a tragic incident, a 13-year-old girl died after she drank a soft drink laced with "extremely high levels" of MDMA, a court heard Thursday.

Eboney Cheshire suffered a seizure after she had a bottle of Lucozade. The girl was rushed to a hospital after her mother saw her having seizures while she was in bed, 7News reported. The incident took place on Dec. 2, 2018, in Bootle, a town in England.

The girl's mother thought the seizure was due to fever. She had "cold-like symptoms" days before her death, the Coroner's Court in Bootle heard Thursday.

Despite getting treatment, the girl died and doctors said it was a drug-related case. Later, the cause of death was determined to be "MDMA ecstasy toxicity."

During the investigation, police officers found residue from powdered MDMA in the Lucozade bottle. But they could not find any evidence suggesting someone else was responsible for the death.

"The conclusion is that of a drug-related death. The police investigation has concluded and no arrests have been made for the supply of drugs. There was no evidence other than Eboney had taken the ecstasy herself," said Julie Goulding, senior coroner for Sefton, Knowsley and St. Helens, 7News reported.

The girl's mother disagreed with the findings, saying someone might have given the drug to her daughter. She also requested a fresh investigation into the death of her child.

"Should there be fresh evidence, the police will look at the fresh evidence. I have to make my findings on the balance of probability, the medical findings and that the police investigation has concluded... My conclusion is that of a drug-related death," Coroner Goulding added.

In a written tribute to her daughter, the mother said: "You are my best friend, so funny, full of character and so popular. I’m broken without you and our lives will never, ever be the same. My baby girl, I love you more than life itself and your brother is heartbroken. Fly, my beautiful princess. Your mummy is heartbroken. I hope you realize how much I love you and how I would have swapped places with you in a heartbeat. I begged them baby girl, but they wouldn't let me."
