According to CPD, SC Ports Authority surveillance footage showed Zito and Gamber being first struck by Carlson’s Chevrolet truck and then hit again by Gentilin’s car 30 minutes later.

Carlson drove away from the scene, according to the CPD, and later crashed his truck in a ditch in West Ashley and fled on foot. Officers were able to locate his vehicle.

Carlson was charged with two counts of reckless vehicular homicide and leaving the scene of an accident resulting in death. His bond was set Tuesday afternoon at $600,000.

Gentilin was released on a $150,000 bond posted on May 2.

Zito was a student at the College of Charleston and Gamber was visiting for the weekend.

Gamber's mother, Nicole Gamber, called the women "bright lights" and said they "weren't done shining."

Services for the women have been held − Zito’s on May 3 and Gamber’s three days later on May 6.
