As manhunt for masked gunman in Chicago continues, authorities increase reward to $16,000

The gunman allegedly killed two men in what police believe are random shootings.

The reward for the capture of a masked gunman who allegedly killed two people in Chicago is up to $16,000, authorities said.

The city's office of the Bureau of Alcohol, Tobacco, Firearms and Explosives added $5,000 to the reward for information about the suspect, the agency announced Saturday. The ATF portion of the reward is in addition to $10,000 and $1,000 offered by Jewish Federation of Metro Chicago and Cook County Crime Stoppers, respectively.

Police have been hunting the gunman for a week now, ever since a 73-year-old man walking his dog was shot to death Sunday in the city's Rogers Park. Douglass Watts was shot in the head, ABC Chicago station WLS-TV reported.

The next day, a 24-year-old man was also shot in the head, the station reported. Eliyahu Moscowitz was also shot in Rogers Park.

The shootings appear to be random, police said.
