An explosion at the Bristol Health & Rehab Center outside Philadelphia killed at least two people, including nursing assistant Muthoni Nduthu.

BUCKS COUNTY, PA ‒ A day after multiple explosions at a Pennsylvania nursing home killed two people and injured 20 others, authorities surveyed the extensive damage and began identifying the victims.

Muthoni Nduthu, 52, was named by the Bucks County Coroner’s Office as one of the two people found dead inside the Silver Lake Nursing Home, also known as the Bristol Health & Rehab Center, after a pair of explosions partially collapsed the facility on Dec. 23.

Nduthu, a nursing assistant at the facility, was a mother of three who was featured in news stories over a decade ago when she bought her home through the local branch of Habitat for Humanity. Clinton Ndegwa, one of Nduthu’s sons, declined to comment when reached by phone, reported the Bucks County Courier Times, part of the USA TODAY Network.

The deadly incident began around 2:20 p.m., when the first blast trapped dozens of residents inside the two-story building and triggered an intense search-and-rescue effort. Firefighters arrived on the scene and pulled frightened residents from windows, stairwells and elevator shafts as the building erupted into flames.

After first responders rescued two people from the building’s collapsed basement, a second explosion rocked the facility, producing another ball of fire and spewing more smoke into the air, said Bristol Township Fire Marshal Kevin Dippolito.

Two people, including Nduthu and a resident who has not yet been publicly identified, died from their injuries. At least 20 others were injured and over 100 residents have been displaced. The facility has more than 170 beds, though it’s not clear how many residents and staff were in the building at the time of the explosions.

Search teams ceased their operations hours after the explosion, after all residents and employees were accounted for. The next day, officials seemed to still be surveying the scope of the damage as members of various government agencies, including the National Transportation Safety Board, walked through the scene and snapped photos.

Pennsylvania Gov. Josh Shapiro said authorities believe a gas leak led to the “catastrophic” blast. Crews for PECO, the local energy company, were responding to reports of a gas odor at the nursing home just before the first explosion was reported.

“PECO crews shut off natural gas and electric service to the facility to ensure the safety of first responders and local residents,” the company said in a statement. “It is not known at this time if PECO’s equipment, or natural gas, was involved in this incident.”

An investigation into the cause of the blasts remains underway.

Shapiro and other officials described a heroic rescue effort that saw first responders hoist residents over their shoulders and carry them away from the burning building.

“In the immediate moments after the explosion, you saw what real heroism is all about,” Shapiro said. “Firefighters rushed to this scene in order to contain the explosion, in order to put out the fire, and most importantly, in order to rescue people.”

Residents who live near the facility said they could feel the explosions from inside their homes.

Joe Westergon, who lives a few blocks from the facility, told the Bucks County Courier Times that he helped carry six injured residents to safety.
