STOCKTON, Calif. — The Stockton Police Department confirmed Friday there is no connection between the Stockton killings suspect and the individual who killed two people in Chicago’s Rogers Park neighborhood, according to KTXL.

“We did our due diligence reaching out to Chicago PD based off the videos we have seen of their suspect. At this time though, we do not have anything linking the two investigations,” Stockton Police Department Officer Joseph Silva said.

The Rogers Park murders happened in the fall of 2018, the suspect known as “The Duck Walk Killer.” A person approached Douglass Watts and shot him while he was walking his dogs near his home in the 1400 block of West Sherwin Avenue. The next day, Eliyahu Moscowitz was shot while he was walking on a path in the 1100 block of West Lunt Avenue.

Both men had been shot execution-style. Police said the same gun was used in both killings.

Beginning in April of last year, six people have been killed in Stockton and Oakland. The last attack happened late last month. Ballistics link all of the killings.

Stockton police have pointed out the man’s unusual gait, uneven stride and upright posture. Chicago police noted distinguishing characteristics in “The Duck Walk Killer.”

The killings were believed to possibly be connected, but Stockton police have confirmed they are not.

A $125,000 reward is being offered for information that leads to the Stockton serial killer.
