Bobb, who was convicted in San Diego County, was rushed to hospital after the attack, where he was pronounced dead shortly afterwards.

Bobb was struck in the head multiple times.

Watson has served 10 years of a life sentence for first-degree murder and discharging firearm causing great bodily injury or death.

Watson also attacked a second inmate identified as Graham De Luis-Conti, 62 who was also pronouced dead in hospital.

De Luis-Conti had been imprisoned since June 2001 after receiving a life sentence for aggravated assault against a child under 14
