How to spot the signs of an early morning mass in New York City

The sign at the front of the New York church that is said to have sparked the mass-killing rampage of Ismael Omar Mateen says ‘Peace for all.’

But when the sign goes up, it also says ‘No peace until all the dead are out.’

Ismaele Omar Matein, who was killed on Monday, was a U.S. citizen born in Florida.

The church is located on the edge of the city’s Little Italy neighborhood, close to the waterfront.

The congregation was reportedly packed at the time of the mass shooting, which killed at least 50 people and injured at least 200 others.
