A foundation created to honor a firefighter killed on Sept. 11 has raised enough money to pay off the mortgages of two slain New York Police Department officers.

The Stephen Siller Tunnel to Towers Foundation says $860,000 has been donated, and another $150,000 has been pledged.

Foundation officials made the announcement Wednesday at an event with the widows of Detective Rafael Ramos (rah-fy-EHL' RAH'-mohs) and Wenjian Liu (WEHN'-jihn LOO').

Liu's widow and Ramos' sister expressed their appreciation. The crowd was made up largely of police officers, including members of the men's precinct.

The foundation says the money will be used to pay off mortgages and make repairs to the homes, with any extra going to the two families.
