BROOKLYN - Four men were wounded overnight in four separate Crown Heights shootings.

The rash of gun violence put an end to an already violent weekend in Brooklyn. Police say that a total of 13 people were shot between late Friday night and early Monday morning, the same weekend that the NYPD held a local gun buyback event.

According to police, one man suffered a gunshot wound to the leg just after midnight on Grafton Street, not long after a shooting on Bainbridge Avenue.

A third man was grazed in the foot at around 12:40 a.m. at 1565 Nostrand Ave., and is also expected to be OK. The last victim was shot in the face at around 1 a.m. on Park Place, but is expected to survive.

All of the shootings remain under investigation, and no arrests have been made.
