Another senseless shooting has left 12 people dead, including sheriff’s deputy Sgt. Ron Helus, after a lone gunman opened fire at the Borderline Bar & Grill in Thousand Oaks, Calif., on Nov. 7.

Many country stars, including Loretta Lynn, Charlie Daniels, John Rich, Brad Paisley, Zac Brown and more, sent out their thoughts and prayers to the victims and their families.

Due to the tragic events in the #CaliforniaBarShooting I will be postponing my press run in NYC so we can all focus on the situation at hand. I’m heart broken for those who were killed or injured, and their families and friends in California.

Waking up in NYC to the terrible news in California that 12 were killed in a country bar last night. 1 officer killed in the line of duty as he ran toward the shooter to save lives. Join me in asking the Holy Spirit to pull those families close this morning. #Californiashooting

Another Blue Knight was lost last night. He died in the act of protecting and serving, as so many of his brothers and sisters have before him.
Sgt. Ron Helus, you died saving lives
There is no higher calling
Rest In Peace
Sincere condolences to the family and coworkers
