SAN BERNARDINO (California) • An investigation into the shooting rampage that left 14 people dead at a holiday party in southern California last week has turned to a small lake near the scene of the massacre, where divers were searching for evidence.
The Federal Bureau of Investigation (FBI) also revealed that investigators were looking into any possible connection between one of the two killers in San Bernardino and four men arrested in 2012 in a separate federal terrorism case brought in nearby Riverside.
The underwater search stemmed from unspecified leads indicating that the married couple who carried out the shooting spree had been in the vicinity of Seccombe Lake in San Bernardino on the day of the killings, said Mr David Bowdich, assistant director of the FBI field office in Los Angeles.
Mr Bowdich said he would not discuss the "specific evidence we're looking for", but CNN reported that investigators were seeking a computer hard drive that belonged to the couple, who the FBI has said were inspired by Islamic extremists.
Mr Bowdich said investigators had already combed the surrounding park, and the search of the lake by FBI and Sheriff's Department divers could take days.
