VIDEO: A new strategy unveiled Tuesday aims to use previous fire investigations to prevent similar fire tragedies from happening again. U.S. Fire Administrator Lori Moore-Merrell traveled to New York City to honor the 17 lives lost in last year's tragedy at the Twin Parks building. It was the first stop in a tour of some of the deadliest infernos. She said the tragedy in the Bronx highlights an unfortunate truth about fires. "It disproportionately affects our most vulnerable population," Moore-Merrell said. The new national strategy to quell America's fire problem includes investing in a national program to address the firefighter shortage and improve diversity. The plan also involves cracking down on code enforcement. "When a fire occurs, we're going to look at those fire safety features and often where the building itself may have failed long before firefighters arrived," Moore-Merrell said.
