(CNN)San Francisco police have doubled the reward for information leading to the arrest of a suspected serial killer known as "The Doodler" who targeted members of the city's gay community in the 1970s -- including a possible sixth victim publicly identified Thursday.
The reward for information leading to the "identification, apprehension and conviction" of the Doodler now stands at $200,000, the SFPD said -- 48 years to the day the killer's first victim was found.
Police said their investigation has identified a potential sixth victim, Warren Andrews, who was assaulted and discovered unconscious at Lands End park in April 1975. Andrews never regained consciousness, police said, and died about seven weeks later.
The idea that Andrews could be a victim of the Doodler was explored in a San Francisco Chronicle series and podcast last year.
