Two men were killed and two others were wounded when gunfire erupted in northern New Jersey yesterday.

The motive for the shooting in Paterson was a mystery, and authorities said it was not known if more than one shooter was involved.

Taheen Taylor and Dashon Adamson, both 22, were killed in the shooting, said Paterson cops. It occurred at about 3:30 a.m. on Summer Street, not far from the city library.
