please send someone in, and if not, let us go in. >> reporter: this is the rosenbergs, shuly, yehuda, and shana. they say they feel helpless, and they're not okay with that. their father, harold, is a widower. he lived alone on the second floor of the building. his daughter malky and her husband, benny weiss, were also there, visiting from new jersey on vacation. i asked the fire marshal why aren't you just taking rocks off and digging down? he said that puts more pressure so we're going from underground in the parking garage to dig a hole and a tunnel through there. >> when i herd that i said, "if it was your father and your sister and your brother-in-law, would you send four firemen under the tunnel?" >> reporter: they want to see more crews digging more often, and this afternoon they did, just as yehuda collapsed and was treated by paramedics. they snapped this photo of what they say is a chair from their father's condo which was across from the pool in an area not covered in rubble. that's part of the reason they believe their family members could, could still be alive.
