Investigators say that Cassandra Head was hit by a dark-colored SUV while using a crosswalk at Martin Luther King Jr. Drive and Bakers Ferry Road on Tuesday morning. The driver of the SUV did not stop, and police say the vehicle may have been seen heading in the direction of Fairburn Road.
Police said that they have identified a suspect, but no arrests have been made.
Head was a postal worker, a mother of five and grandmother of 16, according to her family.
"I'm just hurt. It's just so unexpected so unexpected. I can't imagine this and it's still…hard to grasp," said Curtis Head, Cassandra's younger brother.
Luretha Slaton is the manager at the post office where Cassandra worked for 14 years.
"She was the carrier that everyone loved. She loved her job. She loved coming to work," Slaton said.
Curtis Head also works for the US Post Office. He admits that he was influenced by his hard-working sister. The family says Cassandra had been catching the bus since her car broke down last Wednesday.
"You had to be heartless. You had to have no compassion. That is an uncompassionate person to hit something -- I don't care what it is dog or cat," Curtis Head said.
Head's family is encouraged that the police have identified a suspect but they say they won't have peace until an arrest is made.
Anyone with information on the case is urged to contact authorities.
