ASHEVILLE, N.C. -- A driver, now identified as an Asheville firefighter, shot a bicycle rider because he was angry the man was riding with his child on a busy road, Asheville police said. The shooting happened Sunday morning on Tunnel Road. Officers said the victim was riding with his wife and had his 3-year-old son in a child seat attached to his bicycle when a driver approached him. Police said the driver, Charles Diez, claimed he was upset that the victim was bike riding with his child on the heavily traveled Tunnel Road. Diez pulled a gun and opened fire, hitting the victim in his bicycle helmet, according to police. They said the bullet penetrated the outer lining of the helmet but did not actually hit the victim's head. Police arrested Diez and charged him with attempted first degree murder. His bond was set at $500,000. Diez has been a firefighter with the Asheville Fire Department since 1992, according to officials. On Monday, they confirmed he has been placed on paid investigative leave pending the outcome of this investigation.
