On January 12, 2010, three people were killed and two others critically injured in a shooting at a Penske truck rental business in the city of Kennesaw, Georgia, United States.

The shooter, Jesse James Warren, a 60-year-old former employee, walked into the Penske truck rental business Tuesday afternoon wearing camouflage.

[9] Warren had delusional beliefs, including that the Penske corporation had stolen US$500 million from him, which he believed the US military had given him for inventing Wi-Fi.

[8] Zachariah Werner, who was paralyzed in the shooting with a bullet lodged in his brain stem, filed a $20 million lawsuit against businesses related to the Penske facility, and Warren, in 2011.

The suit alleged that the Penske Corporation had been warned on several occasions that Warren had plans to harm other employees, but failed to provide adequate security.

[12] The widow of another victim filed a separate lawsuit seeking unspecified damages, claiming that the company knew Warren had been making death threats.

[5] The Penske facility planned to reopen with limited services the following Friday, and to be fully operational by Monday.
