Foundation that supports fallen first responders to pay off mortgages for slain agents.

A foundation that supports first responders and their families is raising money to pay off the home mortgages of the two FBI agents who were killed in Sunrise.

Tunnel to Towers, a foundation set up for first responders after 9/11, will pay off the mortgages for Laura Schwartzenberger and Daniel Alfin, the FBI special agents who were killed while serving a warrant in a child pornography investigation.

The foundation lifts the financial burden of a mortgage, which is usually the greatest monthly burden they have, said Trevor Tamsen, a spokesman for the foundation.

“They left behind spouses and young children, and hopefully this will be one tiny bit of peace of mind for the families of those who went out every day to protect our children,” he said. “They were two of the best who dealt with the worst, bringing child pornographers to justice, so this was an easy one for our foundation.”

Paying off a family’s biggest monthly bill prevents them from having to make hard decisions, such as moving schools, leaving a support system behind, or moving out of the home where they made so many family memories, Tamsen said.

Those who want to donate can do so at the foundation’s website at https://tunnel2towers.org/. Subscribers can pledge $11 a month to help pay off the homes of other fallen first responders.

The foundation was established by the family of Stephen Siller, one of the first responders who lost his life trying to protect people on 9/11, while he was off duty. His squad had already left from Brooklyn, so he grabbed his gear and took his personal car to the tunnel into the city, but it was closed. He ran the three miles underground from Brooklyn to the Twin Towers. He was survived by his wife and children, Tamsen said.

His siblings developed the foundation in his name and started the In the Line of Duty Program, which provides mortgage-free homes to the nation’s catastrophically injured veterans, first responders, and Gold Star and fallen first responder families with young children, like the two FBI agents. Both had spouses and young children.

To mark its 20th anniversary, the foundation promised to deliver 120 mortgage-free homes to those killed or hurt in the line of duty.
