STATEN ISLAND, N.Y. -- When she found a pile of feces just steps from her home one morning a few weeks ago, an Eltingville woman assumed someone didn’t pick up after their dog.

When the same thing happened just days later, she got suspicious and checked her security camera.

What she found shocked her: A man, who she said she has never seen before, squatting with his pants down at the curb in front of her house.

“I couldn’t believe what I was seeing,” said Andrea Rosenblum, 48.

The concerned resident shared videos of the two different incidents in which a man, with a similar appearance and clothing, unfastens his pants and pops a squat.

In the first incident on July 13 at around 1:30 a.m., a man seen walking on the sidewalk wearing light pants and a dark T-shirt stops and looks around. He then leaves what looks like a shoulder bag on the grass and a plastic bag on a brick fence. He proceeds to unzip his pants in the street between two cars, inches from the curb, and squats. He pulls up his pants, then leaves after picking up both bags.

Thinking that someone didn’t curb their dog, Rosenblum’s husband picked up the feces with a plastic bag and what she described as “a steady hand.”

Four days later, the family made a similar discovery.

In the second video on July 17, a man appears at around 12:30 a.m., this time stepping on the grass right next to the sidewalk. He is seen unzipping his pants, squatting and walking away.

That is when Rosenblum and her husband decided to rewind their security camera footage to figure out what really happened.

“It was disturbing and actually a little creepy because it happened while my family and I were sleeping and this was going on right outside the house,” she said.

Concerned about the safety of her two children, 12 and 9, who play outside quite often, Rosenblum decided to go to her local precinct, but there is very little the police can do, the resident said.

“[I am concerned about kids] stepping in it because it is human feces and I don’t know who this person is,” she said.
