THOUSAND OAKS, Calif. (AP) — The Southern California bar where a gunman killed 12 people says on its website that it's been in operation for more than 25 years.

The Borderline Bar and Grill says it has the largest country dance hall and live music venue in Ventura County, which is north of Los Angeles.

The bar was holding its regular "College Country Nights" Wednesday night when the gunman dressed in black opened fire inside the bar.

The bar includes a large dance hall with a stage and a pool room along with several smaller areas for eating and drinking.

It is popular with students from nearby California Lutheran University who enjoy country music.

It is also close to several other universities, including California State University Channel Islands in Camarillo, Pepperdine University in Malibu and Moorpark College in Moorpark.
