A Baltimore Gas and Electric Co. contractor will be laid to rest Sunday, a week after he died in a gas explosion that rocked a Bel Air neighborhood.

José Rodriguez-Alvarado’s funeral services are set to be held at Mt. Rainier Christian Church/Emanuel Spanish Seventh-day Adventist Church in Mount Rainier in Prince George’s County, with a visitation scheduled to start at noon and run to 5 p.m., when the funeral will begin.

Rodriguez-Alvarado, a Columbia resident who worked with a crew of linemen at Arbutus-based Hammer’s Powerline Maintenance, died on the job Sunday in the gas explosion that leveled a house in Bel Air, also killing the homeowner and displacing roughly a dozen residents. Rodriguez-Alvarado, originally from El Salvador, was 35. The homeowner, Raymond C. Corkran Jr., 73, was described by neighbors as an “anchor” of the Arthurs Woods Drive community.

A fundraiser was set up by Rodriguez-Alvarado’s brother, Carlos Garcia, to bring Rodriguez-Alvarado back to El Salvador. There, the utility worker’s mother “who will be waiting to give her last farewell,” wrote Garcia, who did not return a request for comment.

Colleagues remembered Rodriguez-Alvarado as a worker who could brighten their day with a friendly demeanor and a smile that spread.

Eric Crawford, a lineman who knew Rodriguez-Alvarado through the industry, remembered the utility worker as also being a supportive husband and father.

Through a spokesperson, Harford County Executive Bob Cassilly said he had met with the BGE contractor’s family after the Sunday explosion.

Investigators from the National Transportation Safety Board were still on the scene Tuesday trying to make sense of what happened. The Maryland Office of the State Fire Marshal and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives were finished with their on-scene investigation, but were continuing their probe of the direct cause and origin of the explosion.

The NTSB’s probe of the pipeline and equipment will focus on a broader scope and take longer, with most investigations taking over a year to finalize. The probe by the state fire marshal’s office and the ATF is more routine, weeding out any potential criminal activity and ultimately determining the basic cause and origin of the blast, a spokesperson said.

State investigators “are confident” a gas leak originated outside the house, said Master Deputy State Fire Marshal Oliver Alkire. But, they’re still investigating when that gas leak started and how it was ignited.
