Sacramento Police Department messages on social media did not confirm the death, but multiple news outlets reported a fatality.
The suspect fled the scene, police wrote on Twitter, adding, “There is no active threat at this time.”
Police said it was “NOT an active shooter incident.”
The wounded person was taken to a trauma hospital with life-threatening injuries, FOX 40 of Sacramento reported.
The victims were an adult man (who was killed) and a teenager, according to the Sacramento Bee.
Video of the incident showed the shooter, who appeared to be between 18 and 25, approached two people at the mall and opened fire on them, police said. He then ran out of the building.
He was wearing a dark-colored hoodie or jacket and police believe he was driving a red Toyota Camry from the 1990s.
The Arden Fair mall, where the shooting occurred, was evacuated after the incident, the Bee reported.
"We are awaiting more details on tonight’s incident from @SacPolice," Sacramento Mayor Darrell Steinberg tweeted shortly after the shooting. "We are deeply concerned by the increase in gun violence in Sacramento and other cities during the pandemic, and have supported increasing our efforts to reach young people at risk. A gun is never the answer."
