ROOSEVELT ISLAND, N.Y. — New surveillance video shows the moment shots were fired into the night sky around the same time a round of shots hit a luxury high-rise apartment on the Upper East Side.

Detectives continue to investigate, looking for any information on the shooter who took aim at the Upper East Side building.

Authorities are looking to identify the man and woman who were seen on surveillance footage walking along River Road on Roosevelt Island around 1 a.m. Saturday, the same time the round of shots hit the 32nd floor of One East River Place.
