Four people are confirmed dead, and a fifth person remains unaccounted for after an explosion in Plum, Pennsylvania, destroyed several homes Saturday. 

Addressing reporters at the scene late Saturday, Plum Police Det. James Little said all activity at the site was suspended for the evening due to the weather, darkness and concern for responders. "At this point, we have confirmed four deceased and one person is still unaccounted for," he said. 

Three additional individuals were transported to area hospitals. Two individuals were transported in stable condition and have since been released from the hospital. The thirdremained in critical condition as of Saturday night, officials said. 

Investigators have yet to disclose the suspected cause of the explosion or other details. Crews were expected to resume activities Sunday morning, Alleghany County wrote on X, formerly Twitter. Another press conference was scheduled for noon at the Plum Municipal complex. 

THREE MISSING, THREE HOSPITALIZED AFTER HOUSE EXPLOSION ROCKS PITTSBURGH SUBURB

At approximately 10:23 a.m. Saturday, county 9-1-1 received a call from the Rustic Ridge Drive and Brookside Drive in Plum Borough reporting a house explosion with multiple injuries and several houses on fire. First responders from the police and fire department arrived at the scene and reported that there were people trapped under debris and that it appeared as if one house had exploded, and two others were engulfed in fire. Multiple other homes were damaged with windows blown out.

County officials said three structures were destroyed and at least a dozen more were damaged in some way. Water tankers were at the scene from both Allegheny and Westmoreland counties and 18 different fire departments. The county's Emergency Management officials and Fire Marshals were also at the site.

Crews had been working on extinguishing nearby structures as gas lines were secured.

George Emanuele, who lives three houses down from the home that exploded, told the Tribune-Review that he and a neighbor went to the home before the fire got out of control, where they found a man laying in the backyard and dragged him away from the scene.

Rafal Kolankowski, who lives a few houses away, told the Pittsburgh Post-Gazette that the explosion broke the windows in his house and knocked him and his wife to the ground.

After recovering and checking on his son, Kolankowski went outside and a woman told him another female had been upstairs and a man was in the basement. The other woman later emerged covered in white ash, but the individual in the basement had not yet exited, he said.

"It’s just tragic, I mean, it looks like a war zone — it looks like a bomb hit our neighborhood, and it’s just unfortunate," Kolankowski said. "I was just with some of the neighbors yesterday, right, and now this happens."

Jeremy Rogers, who lives two doors down, told the paper he had been out shopping when he got an alert about a problem at his house and saw "all sorts of stuff flying around." His family was able to get out safely, and he was allowed to go inside quickly to rescue his dog, although he could not locate the family's three cats.

Texas lawmakers are at odds over whether the Lone Star State can be found liable for the death of a 3-year-old Venezuelan girl traveling on a relocation bus sent by the state from Brownsville to Chicago.

The girl was riding the bus paid for by Texas when she became ill. She was later pronounced dead at an Illinois hospital Thursday night.

Now, lawmakers are sounding off on if they think the state can be found at fault for the child's death, according to News 4 San Antonio.

"What I’m being told is that people are screened and that clearly didn’t happen here. Whether this child was screened or not remains to be seen," Texas State Senator Roland Gutierrez told the outlet.

The Texas Department of Emergency Management oversees the bus trips to relocate migrants to sanctuary cities, which Republican Gov. Greg Abbott has previously said will continue until the federal government fixes the immigration crisis at the U.S.-Mexico border. 

The department said in a statement that everyone boarding the bus had their temperature checked and was asked if they required medical attention.

"At some point, they find out after the fact, that the child had been sick, and the family was giving the child some kind of Pedialyte and maybe administering some kind of medications," Gutierrez said.

Gutierrez said it is unknown if the people on the bus were aware that the girl was sick. The senator said he believes Texas is at fault in the girl's death.

"This child died because in all likelihood they were on a bus that they could not get out of," Gutierrez said.

Attorney Tim Maloney said that key detail is important in determining if the state has any liability.

"It's unthinkable that you would have a 3-year-old in severe medical distress, that it wouldn't rise to an emergency situation immediately," Maloney told News 4 San Antonio.

But U.S. Rep. Chip Roy, R-Texas, said the state is not responsible for the child's death last week.

"Bus rides aren't dangerous, politically-motivated encouragement of human caravans across a continent that overwhelm our border operations and cause deaths every day are dangerous," Roy said in a statement.

Maloney said, "A criminal prosecution against a government entity, unless it falls into a civil rights violation, there is very few governments that can be held liable criminally." The lawyer said he believes it would be extremely difficult to fault the State of Texas for this tragedy, but that the child’s death could result in a ban, at least temporarily, on the migrant relocation buses to cities in other states.

"A federal judge can issue a temporary injunction and try to go to a mini-trial on the merits to determine whether or not that should be extended permanently," Maloney said.
