Jersey City police have taken seven illegal guns off the streets and made 11 related arrests since Sept. 7 as part of a collaborative effort between specialized police units and the Hudson County Prosecutor’s Office.

“When people have illegal firearms what usually follows is a shooting, so every time we can intercept these weapons, it’s a shooting our police officers have prevented,” Jersey City Police Chief Michael Kelly said Monday.

The chief said the effort to rid the streets of illegal guns involved intelligence gathering that led the department’s Street Crimes Unit, Cease Fire Unit, and patrol officers to areas of the city most vulnerable to gun violence.

“It’s really good, collaborative police work,” Kelly said. “We have been stressing the intelligence end for the Jersey City Police Department for two years and it’s a large reason why gun violence has been significantly reduced.”

Kelly, who took over the department in January 2018, noted there was a 30 percent reduction in shootings in the city in 2018 and that this year’s numbers show there will be an additional reduction equal to last year’s drop.

All 11 people who were arrested were charged with unlawful possession of a weapon and possession of a weapons for an unlawful purpose, Kelly said, adding all guns seized were loaded.

On Sept 7, police took Ferdinand Jacobs, 24, of Stevens Avenue, into custody at Warner and Rutgers avenues and seized a .32 caliber revolver.

Jacobs was additionally charged with possession of heroin, Kelly said.

On Sept. 9, police arrested Davis Simmons, 21, of Ocean Avenue, at Winfield Avenue and seized a .380 caliber handgun, Kelly said.

In a separate arrest on Sept. 9, police took Lamarr Fishburne, 34, of Queens, into custody at Bergen and Bostwick avenues and seized a 9mm handgun, Kelly said.

Finally, in a third arrest on Sept. 9, police apprehended Noah Hill, 21, of Garfield Avenue, on Wegman Parkway and seized a .22 caliber handgun, Kelly said.

The following day, police arrested Shariyf Higgins, 37, of Union Street, during a motor vehicle stop on Union Street and seized a .32 caliber handgun, Kelly said.

On Sept. 11, police arrested two more adults and a juvenile at Neptune and Ocean avenues. Taken into custody were Alfreda Williams, 39, of Neptune Avenue; Rodney Williams, 38, of Corona, New York; and a 17-year-old boy, Kelly said.

Finally, on Monday, police took three people into custody at Astor Place and Summit Avenue during a motor vehicle stop. Arrested were Yusef Mathis, 29; Jalil Burns, 32, of Arlington Avenue, and Yairisa Lizardo, 25, of Summit Avenue, Kelly said.

During Monday’s arrests, a .40 caliber handgun that was reported stolen in Pennsylvania was recovered by police. Mathis, Burns and Lizardo were also charged with possession of heroin, Kelly said.
