His death was announced on May 19 on the social media accounts of Stephen Pearcy, the former lead singer of Ratt.

“This morning I’m very saddened to hear about the passing of our dear friend, guitarist and musician Christopher (Chris) Hager,” Pearcy posted on Instagram. “Chris and I started Mickey Ratt together in San Diego 1977 and in moving to L.A. actually created the band RATT in 1981.

“Chris was an amazing person, a great guitarist, songwriter and so committed to being just that. He went on to create a few projects over the years with Sarge, Rough Cutt, Woop and the Count and our solo project Pearcy/Hager. We were actually working on new songs recently, and they will be heard. I’m at loss my friend, we’ve been through a lot together. God bless you brother,” he added. “As of this time the family would respect privacy.”
