NEWARK — The death toll from the city's unusually violent holiday weekend has climbed higher still after an Irvington man died from injuries he sustained in a shooting on Friday, according to authorities.

Anthony Crooks, 30, died Sunday morning after being shot multiple times in the area of Avon Avenue and Ridgewood Avenue on Friday night, a Essex County Prosecutor’s Office confirmed.

Crooks’ death pushed the number of murders in the Newark since Friday to four, and the city’s total for the year to 85.

A 23-year-old Irvington resident and 36-year-old Orange woman were gunned down in separate incidents on Saturday night, one of which wounded three others outside West Ward bar Oasis 93.

On Sunday, three people were shot on South 20th Street, one of whom died shortly after arriving at University Hospital. The incident took place just a block away from where Williams was killed a night earlier.

No arrests have been made in any of the cases, which prompted Mayor Ras Baraka to announce a number of changes to policing strategies in response to what he called a "state of emergency" in the city.

Officials did not cite Crooks’ death during a press conference on the wave of violence this morning, saying that at least 11 people had been shot since the Thanksgiving holiday, but that only three had died.

Authorities have declined to say whether any of the shootings are related, though Police Director Eugene Venable told reporters this morning that “internal strife” among local street gangs may be to blame for some of the recent violence.
