Mexican Olympic medalist Noe Hernandez remains stable three days after being shot in the head at a nightclub in metropolitan Mexico City, although his condition is still life-threatening, doctors said Wednesday.

The 34-year-old former race walker, winner of a silver medal at the 2000 Summer Olympics in Sydney, lost vision in his right eye as a result of the attack but has responded favorably in recent hours.

Surgeons said Hernandez has awoken and is able to move his extremities and respond to basic commands but they are not yet able to determine if he suffered brain damage.

Dr. Carlos Castillo told reporters his team must wait until the ventilator is removed before they know if Hernandez is able to talk, adding that they will decide on his treatment at that time.

Hernandez finished second to Poland's Robert Korzeniowski in the 20-kilometer race walk in Sydney and recorded his personal-best time of 1:18:14 in that event at the 2003 IAAF World Championships in Athletics in Saint-Denis, France.

The 34-year-old Hernandez serves as sports secretary of the executive committee of the governing Institutional Revolutionary Party, or PRI, in Mexico state, which surrounds the Federal District and forms part of the Mexico City metropolitan area.

He was shot Sunday at a nightclub in Los Reyes La Paz, a city located about 30 kilometers (nearly 19 miles) from the Mexican capital.

The shooting - which is currently under investigation - also left another individual wounded, police said. EFE
