Authorities say a recently fired employee opened fire at a transportation company on the outskirts of Houston, killing one employee and injuring another before fatally shooting himself, the AP reports. Harris County Sheriff Ron Hickman said Wednesday that the gunman had been fired earlier in the day, then returned with a gun to the Knight Transportation office in Katy, about 20 miles west of Houston. Hickman says the man opened fire, killing one person and injuring another. Hickman says the man then shot himself. The sheriff didn't release the name of the gunman or the victims. Numerous patrol vehicles surrounded the facility as police continued to search the office, while nearby schools that had been put on lockdown were eventually reopened, NBC News reports.
Hickman says the weapons involved in the "retaliatory act" were a shotgun and a pistol, though the gunman apparently used only the shotgun in the shootings. Cops say the victim who survived was a Knight worker who got shot in the face with a bean bag. "Other than [the shooter] was terminated, we don't know anything about him," Hickman says. "He parked right outside the building and came right in." A message left with Phoenix-based Knight Transportation wasn't immediately returned. The company provides truckload transportation services.
