Two people who were seriously injured in Friday's house explosion, a 25-year old and a 60-year old, remain in critical condition Saturday. Both men were taken to a burn unit at Brooke Army Medical Center in San Antonio.

A good Samaritan at the scene identified the 25 year old as Randy Conner. Family members identified the 60 year old as Robert Farley.

Following the blast, which happened on the 4800 block of Holmes early Friday morning, both men were taken to Christus Spohn Memorial Hospital, and were later transferred via HALO Flight to the San Antonio burn unit.

The Corpus Christi Fire Department said one of the victims was found in the backyard of the home where the explosion happened. He reportedly had various cuts and punctures and was singed around his face. The other victim had burns to his upper body and his arms and legs. He had been carried to a park across the street from the explosion.

One other person did have minor injuries, but refused treatment.

Local and state Fire Marshals are meticulously sifting through the rubble to determine the cause of the blaze. Residents speculate that it could have been caused by a natural gas leak.

According to the American Red Cross, there are three homes destroyed, 15 homes with minor damages and 55 other homes that were affected. Of those, 36 were apartments with window damage.
