The girlfriend of a man suspected in the near-fatal beating of a San Francisco Giants fan has been arrested in Las Vegas.

Denise Piccione is being held in the Clark County jail on charges of trafficking methamphetamine, possession of methamphetamine, and possession of a dangerous weapon after a weekend arrest at a hotel.

City News Service reports she pleaded not guilty Wednesday.

The 26-year-old Piccione was considered a person of interest after a March 31 beating in a Dodger Stadium parking lot.

A 42-year-old Giants fan, Bryan Stow, is still hospitalized.
