(KTLA) –At least four people were killed and several more were injured Wednesday evening after shots rang out at a historic and popular Orange County biker bar. Among those killed was the suspected gunman, according to the Orange County Sheriff’s Department.

The shooting happened around 7:30 p.m. at Cook’s Corner in Trabuco Canyon, according to authorities.

Dozens of first responders were called to the popular biker bar, which is located at 19152 Santiago Canyon Rd.

Photos posted to social media showed a chaotic and bloody scene inside the historic bar.

Around 9 p.m., Sheriff’s Department officials confirmed that four people were dead at the scene and six people were taken to the hospital, with five needing treatment for gunshot wounds.

Officials said deputies fired on the suspect, who was struck and killed. No law enforcement officers were injured.

Cook’s Corner is a famous motorcycle pitstop located about six miles northeast of Lake Forest. The bar was built in 1884 and has hosted a number of high-profile visitors, including film star and former California Governor Arnold Schwarzenegger.

CA State Senator Dave Min released a statement after the shooting.

I’m heartbroken by the news of yet another mass shooting tonight, this time at Cook’s Corner, a historic bar in the heart of Orange County. My team and I are monitoring the incident and will do everything we can to support law enforcement. Our district is one of the safest areas in the country, and yet we too are repeatedly afflicted with the scourge of mass shootings. An office park in Orange, a church in Laguna Woods, a bar in Trabuco Canyon. There is no place in America that is safe from the scourge of gun violence. There is no community not affected. My heart breaks for the families and loved ones of the victims. We cannot rest until we end gun violence in this country

State Senator Dave Min
