A tragic house explosion in Bel Air, Maryland, on Sunday morning resulted in the deaths of two individuals, including a 35-year-old Baltimore Gas & Electric contractor and a 73-year-old homeowner, whose identity is pending confirmation. The explosion, described as one of the largest seen by a local fire marshal in 18 years, occurred while BGE was investigating reports of a gas odor at the residence. A neighbor sustained injuries but refused transport, while one person remains unaccounted for. Debris from the explosion affected neighboring properties, prompting a significant search and rescue operation. Multiple agencies, including the Maryland Fire Marshal and ATF, are investigating the incident, which is believed to be linked to a gas leak. The house was reportedly about to be listed for sale, and additional details about the explosion are expected to be released as the investigation continues.
