The families of victims of last year’s deadly nursing home fire in Nashville, TN, have settled 28 of 32 negligence lawsuits filed against the facility’s owners, lawyers said Thursday.

Details of the 14 death and 14 injury settlements were not immediately available. Meanwhile, three of the cases are in mediation, and one has not yet entered mediation. Eight people were killed in the Sept. 25, 2003, blaze, and another seven residents died in the following months.

Investigators closed their probe of the fire in June without determining a cause. The facility did not have a sprinkler system, nor was it required to at the time. This and another deadly fire sparked calls from legislators for mandated sprinkler systems in nursing homes.

Support has grown for the Nursing Home Fire Safety Act, which calls for every nursing home and assisted living facility to have a sprinkler system, with funding assistance from Medicare and Medicaid.
