A Florida family is reporting that they have received 16 phone calls from a landline belonging to their grandparents who are still missing in the Surfside condo collapse.

Jake Samuelson told reporters that his grandparents Arnie and Myriam Notkin lived on the third floor of the Champlain Towers in the portion of the condo that collapsed.

Ever since then, the mother began receiving with phone calls from the phone that was said to have been stationed by the Notkin’s bedside.

According to the family’s report, the first call occurred at 9:50 p.m. the same night the tower collapsed.

“We are trying to rationalize what is happening here. We are trying to get answers,” Samuelson told WPLG.

The Samuelson’s say when they answer the phone call, they are only met with with static.

“We were all sitting there in the living room; my whole family, Diane, my mother,” he recalled. “We were just shocked, and we kind of thought nothing of it because we answered and it was static.”

Since Friday, however, the family says they have not received any other phone calls from the number.

As of Monday, the death toll has been raised to 10 with 151 people still missing.

At least four of the deceased have been identified: 54-year-old Stacie Dawn Fang, 83-year-old Antonio Lozano, 79-year-old and Gladys Lozano, and 54-year-old Manuel LaFont.
