The cause of a fire last week at an abandoned tire dealership in Camden, N.J., may take weeks to find, according to local fire officials.
The June 9 fire leveled the former Reliable Tire Co. and most of the two surrounding city blocks. At least 23 buildings had fire damage and more than 20 residents were displaced.
Three firefighters and one civilian were hospitalized for smoke inhalation; none had life-threatening injuries.
On Friday, demolition crews knocked down the instable remaining walls of the building to allow investigators to get to the area where the blaze was believed to have started.
A fire official told local media that firefighters were hampered by near-100 degree heat, lightning and a lack of water supply the brass threading on three hydrants near the blaze had been stolen.
