Emergency, ATF, police and fire crews are responding to a report of a multiple-victim shooting on Wednesday, authorities said. At least 14 people were killed and 17 more wounded. Police said one suspect was “down.”

Within hours, officers were pointing guns at an SUV with shattered windows on a residential street. It was unclear if the incidents were related. Police said shots were fired, an officer-involved shooting occurred, and one suspect appeared to be down.

Other suspects could still be at large.

The shooters used long guns and “came prepared,” San Bernardino Police Chief Jarrod Burguan said during a press conference. Police were initially looking for three suspects, who were reportedly dressed in black.

There is an active scene unfolding in San Bernardino. Preliminary info is a suspect is down, officers are ok. Not confirmed if related.

A man whose his wife worked in the building told KABC-TV that at least one gunman walked into the center and opened fire, the LA Times reported. She was able to lock herself in her office. “They saw bodies on the floor,” he said. https://youtu.be/Sn1Q6nFAcCU

Terry Petit said he got a text from his daughter saying she was hiding after gunfire erupted at the social services facility in Southern California where she works. Petit choked back tears Wednesday as he read the texts for reporters outside the Inland Regional Center. He says she wrote: “People shot. In the office waiting for cops. Pray for us. I am locked in an office.” Police searched people filing out of a building with their hands up before they reunited with loved ones. Ambulances and law enforcement vehicles are racing through the area with sirens blaring.

A police spokeswoman told the LA Times that the suspects were heavily armed and possibly wearing body armor. Several law enforcement agencies converged on the scene, and triage units were being set up in the area. Some people were seen being wheeled away on gurneys, and others filed out of a building with their hands up. A spokeswoman from nearby Loma Linda Medical Center said the hospital was expecting patients momentarily. “We’re all kind of on standby right now – it could be any minute,” spokeswoman Briana Pastorino said.

In October, a gunman killed nine people at a college in Oregon and in June a white gunman killed nine black churchgoers in South Carolina.
