Based on the preliminary investigation, the fire may have been caused by the illegal manufacture of narcotics within the apartment, according to police.

During a subsequent search of the apartment, investigators found suspected hashish oil and marijuana, along with other materials and paraphernalia, police said.

The San Bruno Police Department, in cooperation with the San Bruno Fire Department and the San Mateo County Narcotics Task Force, are continuing to investigate the cause of the blaze.
