Gwinnett County Police Department spokeswoman Cpl. Illana Spellman said Robert Lankford II, 34, appeared to have been wounded Thursday by a gunshot fired by a pickup truck driver he had followed to the gas station, The Atlanta Journal-Constitution reported Saturday.

Spellman said that, according to Lankford, the unidentified man had slammed on his brakes repeatedly while in front of him.

A police report said that after pulling into the station, the pickup truck driver allegedly turned his vehicle around and fired a shot at Lankford while calling him a "long-haired hippie."

Spellman told the newspaper Lankford received medical attention for a gunshot wound to his torso and police were searching for the unknown assailant.
