The parking garage in question IS a high rise. It’s 16+ stories tall.
The stand off was on the second or third floor.
Not sure if that was the ‘shooters nest.’
Roger. I think the shooting came from the parking garage and the last active gunman was forced into the El Centro school, across the street.
In a video, it appeared that the gunman parked an SUV alongside the school, exited the vehicle and began engaging the police, killing one officer that had returned fire from behind a column, but unfortunately- the officer had exposed himself or herself to the gunman’s field of fire, and was subsequently killed at close range.
The gunman then ran around the building’s corner, running to the other end of the building, turned the corner and disappeared inside the school, winding up, on the second floor.
