HOLLYWOOD (KABC) -- A family is searching for their loved one, a 71-year-old man who suffers from dementia, after he went missing at the Hollywood Bowl.

Harrison Ferguson was separated from his group after the performance at the Bowl on Saturday night, prompting the California Highway Patrol to activate a Silver Alert.

His family says he's 5 feet 10 inches tall and weighs about 165 pounds.

He was last seen wearing black and white Puma tennis shoes, light blue jeans, a white and burgundy striped shirt and a grayish blue leather jacket.

His family is offering a $1,000 reward in the case.

Anyone with information about his whereabouts is urged to call 911.
