LOS ANGELES (AP) — A 19-year-old French citizen who was gravely injured when flames tore through a high-rise apartment tower this week died Friday evening at a hospital, authorities said.

The Fire Department announced the death but provided no details.

The Los Angeles County coroner’s office identified him as Jeremy Bru of France. But it had no other details, and there was no immediate word on the exact cause of his death.

Bru was a foreign exchange student, KCBS-TV reported.

Bru was among 11 people who were treated after Wednesday’s fire, mostly for smoke inhalation. Seven of them, including a 3-month-old child and a man in critical condition, were sent to hospitals. There was no updated word on their conditions Friday.

In addition, two firefighters received minor burns as they scrambled to reach the apartment where the blaze began using bottled oxygen, fire Capt. Erik Scott said.

In some dramatic rescues, helicopter crews plucked 15 people from the roof and a ladder was used to save a man who clung to the outside of the building as flames raged in nearby apartments.

The fire displaced 339 residents, and some wondered why the management company didn’t install sprinklers after another destructive blaze seven years ago.

City officials said after the 2013 fire “that it shouldn’t take another tragedy” to get sprinklers into older buildings that are exempt from retrofitting rules, City Councilman Mike Bonin said Thursday. “But it did.”

Bonin introduced a council motion Friday to seek an ordinance that would require sprinklers in residential buildings built more than 50 years ago, before regulations required fire-suppression systems in buildings taller than 75 feet (23 meters).

It’s an issue that officials in other U.S. cities have grappled with in recent years. Honolulu passed regulations requiring stricter safety rules for buildings with 10 floors or more after a fire raged through a 35-story condominium in 2017, killing four people. It was built in 1971, before the city required condos to have a sprinkler system.

In Chicago, a 2015 law required residential high-rises that were built before 1975 to install fire sprinklers. In New York City, many older residential buildings lack sprinklers, a fact that made headlines in 2018 when a fire at Trump Tower killed a resident and injured firefighters.

The Los Angeles City Council has considered expanding the sprinkler requirement for years, but they “petered out in committee,” Bonin said.

Previously, the effort faced objections from building owners who said the fixes would be too expensive and would drive up rents. This time, council members are committed to getting the law passed, and they have the backing of building owners and tenants’ groups, Bonin said.

He said officials hope to find federal grants to cover the installation costs, but if not, he wants to see management companies pick up the tab. For the most part, they are corporations — “not mom-and-pop owners” — that can afford the costs.

Los Angeles Fire Chief Ralph Terrazas recommended in 2017 that sprinklers be installed in all 55 high-rise buildings that still lacked them. At the time, the department estimated that the updates would cost about $6,000 per unit.

“Is someone really going to come to council chambers and argue that the life of a tenant isn’t worth 6,000 bucks?” Bonin asked.

Greg Brown, senior vice president of government affairs at the National Apartment Association, said in a statement that apartment owners face complex and expensive challenges in retrofitting existing buildings.

“Existing apartment buildings already operate under fire codes, required evacuations and safety plans, and annual municipal inspections processes to ensure resident safety,” he said. “Mandating such retrofits would negatively impact an already inadequate affordable housing supply and discourage investment in older housing stock.”

Images of flames spewing from the seventh floor of the Barrington Plaza were eerily similar to those from the 2013 fire that caused injuries and gutted the 11th floor.

Puja Oza and her roommate Dalia Kingsbury got calls and texts from friends about the fire before they heard smoke alarms. Still wearing pajamas, they ran with their golden retriever, Seymour, and their panicked neighbors down 16 flights.

In a hotel the next day, Oza wondered whether a sprinkler system would have doused the flames before they got out of control.

“The fire destroyed three other apartments in the time it took for firefighters to get up there,” she said. “I just don’t understand how it’s not already a law. It’s really ridiculous.”

Tenants filed a class-action lawsuit Thursday accusing the building’s owner, Douglas Emmett Inc., of negligence.

In response to a request for comment on the lawsuit, the fire and the lack of sprinklers, the company said in statements Friday that its “thoughts and prayers are with those who are injured” and its focus was on getting residents back into their homes.

The company said floors 10 through 25 were cleared for residents to return to their units and residents of the lower floors were being accommodated in hotels until further notice.

The statements did not address the lawsuit but said the building had passed its most recent Fire Department inspection and that the company was interested in learning the results of the investigation into the cause of the fire, “which appears to have started inside one of the residential units.”

Landlords neglecting fire safety is an ongoing issue, said Jacob Woocher of the Los Angeles Tenants Union.

“Across the city, we see owners minimize spending on maintenance and upkeep in order to maximize profits, and cutting corners on fire safety is just one particularly egregious way their greed can endanger the lives of tenants,” he said.

The complex has 240 units that range in rent from $2,350 to $3,695 per month, according to Zillow.

The building passed a fire inspection in June, Scott said.
