Italian prosecutors have reopened an investigation into the death of cyclist Marco Pantani after his family presented evidence contending the former Tour de France winner was murdered.

Pantani, who won both the Giro d'Italia and Tour de France in 1998, was found dead in a Rimini hotel room on Feb. 14, 2004. A coroner ruled he died from an overdose of cocaine.

The cyclist's mother, Tonina Pantani, has always claimed her son was murdered, alleging that he was forced him to drink a lethal dose of cocaine dissolved in liquid.

Tonina says, "on one side I'm glad, after many years, finally I'm not shouting into the wind."

But she says "inside me there's also anger, anger and more anger. Why did it take all this time?"

Rimini prosecutor Elisa Milocco will lead the new investigation.
