Three days after a shooting rampage at the Penske Truck Rental office in Kennesaw, Ga. that left three dead and two critically injured, the office reopened on Jan. 15. According to the Atlanta Journal-Constitution, several customers who drove on to the property spoke to the newspaper about the victims, saying they were considered friends.

Former Penske employee Jesse James Warren has been charged in the shootings.

Mechanics Van Springer, 59, and Roberto Gonzalez, 31, died in the shooting. Joshua Holbrook, 27, and Zachariah Werner, 35, were still in critical condition at Wellstar Kennestone Hospital.

Truck driver Jaider Felipe Marulanda, who drove a local food distributor and was there that day to get his truck serviced, was also killed.

Tim Neitzel was returning a truck to the agency on Jan. 15 and said the mood in the office was somber. Neitzel said he narrowly missed being at the facility at the time of the shooting.

Outside the shop, in front of the Penske sign, people have left flowers and small bouquets in memory of the victims.
