The investigation of the Arizona shooting rampage that left a US congresswoman in critical condition was focused Sunday on finding a possible accomplice to the crime that killed six and wounded 14.
Doctors contiued to express optimism about the chances US Representative Gabriel Giffords would survive a shot in the head.
Surgeons in Tucson said a bullet went through Giffords’ head on the left side of the brain, but she was still able to respond to commands. Paramedics got her to surgeons in under 40 minutes after she was shot while meeting with constituents on the sidewalk in front of a supermarket.
Authorities said Giffords, a 40-year-old Democrat, was targeted by a man with a semiautomatic weapon. The chief federal judge of Arizona was among the dead.
Jared Loughner, 22, who was arrested in the case, was described as mentally unstable and possibly acting with an accomplice.
A man possibly associated with the suspect who was near the scene was photographed by a security camera. He was described as white with dark hair and 40 to 45 years old.
Loughner shot indiscriminately at staffers and others standing in line to talk to the congresswoman, said Mark Kimble, a communications staffer for Giffords. The rampage ended after two people tackled the gunman.
The motivation for the crime remained under investigation, officials said
