Plum house fire: Man, 56, dies four days after Rustic Ridge neighborhood was rocked by deadly blast with death toll now at six

A man who spent four days battling for his life in a burn unit became the sixth confirmed victim of the mystery explosion, which also killed his wife, in the Pennsylvania mining town of Plum.

Paul Oravitz, 56, died from injuries suffered in the explosion after being pulled from the rubble just minutes after a fireball engulfed his street. 

Oravitz's wife, Heather, 51, and neighbors Mike Thomas, 57, Kevin Sebunia, 55, Casey Clontz, 38, and son Keegan Clontz, 12, have also died after three buildings were obliterated by the blast just before 10.30am Saturday. 

The 56-year-old was a passionate supporter and treasurer for the town's youth soccer club and remembered fondly by its president, Fred Lucas.

'The world just lost one of the best creations God ever made,' Lucas said. 'I don't know anybody better than him, and I've met a lot of people in my lifetime.

A GoFundMe for the family's two adult children, daughter, Taylor, 23, and son, Cole, 21, has raised over $50,000. 

The cause  of death for all the victims remains pending an investigation by the medical examiner's office.

The remains of the victims have since been released to families for their funerals, according to the Pittsburgh Tribune-Review.

Terrifying footage showed the moment the home on 141 Rustic Ridge Road completely blew apart, causing other properties to go up in flames. 

The home was owned by the Oravitz family. Heather was community development director in the town, which is around 20 miles east of Pittsburgh.

Two more people injured in the blast were treated at a hospital and released.

New doorbell footage shows the moment the home blew apart, causing widespread damage. 

The footage begins with a quiet sunny shot of the street, with no signs of movement.

Moments later, the camera shakes violently from the force of the blast, and debris is launched over the street before falling to the ground like rain. 

The first named victim, Casey Clontz, leaves behind his wife Jen, and daughter Addie, 10. 

The family said in a tribute to them: 'Their smiles and laughter filled their family's and friends' hearts with joy that can never be replaced.'

Relatives did not say why the father and son Keegan were at the Oravitz's property, but explained it wasn't uncommon for them to stop by as they were 'very friendly' with neighbors.

Sebunia was described as a devoted family man who leaves behind his wife, Kelly, and daughters, Emily and Abigail, according to local paper Trib Live. 

'His family came before anything,' his friend Joe Pulcini told the paper. 'His two girls came before everything.'

Borough manager Michael Thomas leaves behind his wife Jackie and their 16-year-old daughter, Trib Live said.  

The mayor told the paper Thomas had recently taught his daughter how to drive a stick shift, describing him as 'probably the best borough manager we had'.

Five people were found dead after a house explosion in western Pennsylvania that destroyed three structures and damaged at least a dozen others, authorities said Sunday

Emergency responders said people were trapped under debris when they arrived to the scene. 

County spokesperson Amie Downs said the blast leveled one house and two others were on fire. 

Fifty-seven firefighters were treated at the scene for minor issues, an Allegheny County official said.

The cause of the explosion is under investigation by the Allegheny County fire marshal's office, along with local law enforcement, with officials warning that the process would be careful and would take time.

The fire marshal's office said in a statement Monday that it was aware of the reported hot water tank issues. The agency planned to investigate the cause of the blast, with the hot water tank issue in mind, and 'along with any and all other possibilities,' the statement said.

The Pittsburgh Post-Gazette reported that the development is on abandoned mine land surrounded by shallow still-producing or abandoned oil and gas wells. 

Two producing gas wells are within about 1000 feet (305 meters) of the home that exploded and a pipeline runs behind the development, but none of those structures have been identified as having been involved in the blast, the newspaper reported.

Michael Huwar, president of Peoples Gas, said official checks by the company indicated that 'our system was operating as designed.'

A GoFundMe has been set up for the Oravitz family, which has raised over $50,000

The state Public Utility Commission said Tuesday it has been monitoring integrity tests of nearby lines by the utility and interviewing utility employees, first responders and residents as well as coordinating the collection of evidence at the scene 'including natural gas service lines and meters.'

Safety engineers of the commission also have been monitoring restoration of electric service as well as the planning and safe restoration of natural gas service. 

A county spokesperson said Tuesday that electrical service was restored by Sunday afternoon to all homes other than the three that were destroyed.
