Complications from Anne Marie Hochhalter's paralysis were a "significant contributing factor" in her death, according to a forensic pathologist.

The Columbine High School massacre has officially claimed another life - nearly 26 years after the US mass shooting.

The death last month of Anne Marie Hochhalter, who was left partially paralysed by two gunshot wounds in the attack, has been ruled a homicide by the Jefferson County Coroner’s Office.

On 16 February this year, the 43-year-old woman died in her Denver home of sepsis - a reaction to infection.

And complications from the paralysis were a “significant contributing factor” in her death, forensic pathologist Dr Dawn B Holmes wrote in a 13-page post-mortem report.

Dr Holmes ruled that “the manner of death is best classified as homicide”.
