stabbing on St. Marks Ave?

edgeoftheslope

Hi all,
On Sunday (6/11), I came home in the early afternoon and my street was blocked off by a zillion police cars. I asked some of the people standing around and they said there was an accident AND a stabbing. The cops were there until late evening.

This happend right in front Helios at the corner of St. Marks and 6th Ave.

I searched NY1, google news, etc... but can find no further info on it.

Were you there? Did you hear anything? What really happened?

It's all pretty strange.

Thanks for your help.
A curious and concerned neighbor.
