SACRAMENTO, Calif. --
Investigators combed through wreckage of an Oak Park home explosion Monday two weeks after the blast injured four Sacramento firefighters.
No arrests have been made and no suspects have been named in connection with the blast, which authorities have labeled arson.
The vacant house, located in the 3800 block of 25th Avenue, blew up on the morning of July 5 as firefighters were entering.
Investigators with the Bureau of Alcohol, Tobacco, Firearms and Explosives, the City of Sacramento Fire Department and arrived at the scene Monday, along with two people with Pacific Gas and Electric.
On dispatch tapes, fire officials also can be heard confirming gas was shut off at the meter after responding to a report of an odor of gas outside.
