NEWARK, N.J. (CBSNewYork/AP) – A string of shootings have left four people dead and eight wounded in Newark over the weekend.

So far, no arrests have been announced in any of the incidents.

Three people were shot dead Saturday.

One man was shot several times outside an Avon Street apartment complex on Sunday afternoon.

Neighbor Patricia Casper tells The Star-Ledger that it sounded like a machine gun and made her fear for her grandchildren’s safety.

Newark recently laid off more than 160 police officers.

Summer often brings a spike in violence in the state’s largest city. In the summer of 2010, there were 35 homicides. Eighty-five people in the city were killed in all in 2010.
