Police say they found 12 pipe bomb devices at a California home being searched in connection with a mass shooting as well as hundreds of tools that could be used to make improvised explosive devices.
San Bernardino Police Chief Jarrod Burguan said at a news conference Thursday that the attackers also left a device at the social service center where they opened fire. The device consisted of 3 connected pipe bombs with a remote control that apparently did not work.
Authorities say Syed Farook and his wife or fiancee killed 14 people at the center Wednesday. The chief says the attackers fired between 65 and 75 rounds at the center. They later died in a gunbattle with police.
Burguan also says the number of people wounded in the mass shooting in Southern California has risen from 17 to 21.

President Barack Obama is ordering U.S. flags to be flown at half-staff to honor the victims of the shooting in California that left 14 people dead.

Obama says it's possible the massacre was related to terrorism but that authorities still don't know. He says it's possible it was workplace-related or that there were mixed motives.

Divorce papers from the parents of one of the San Bernardino, California, attackers reveal an acrimonious split in which the wife accused her husband of being an abusive alcoholic.
The records obtained Thursday by The Associated Press show that Syed Farook's mother, Rafia, described her husband in 2006 as "irresponsible, negligent and an alcoholic."
She said she was forced to move out of her home with three of her children because her husband continually harassed her "verbally and physically and refused to leave the home."
She filed a no-contact, stay-away domestic violence protection petition on July 3, 2006. She alleged that same year that her husband attacked her while her kids were present, dropped a TV on her and pushed her toward a car.

Police and federal agents are for a second day searching a home in connection to the massacre in San Bernardino, California.
A search team combed the residence early Thursday in neighboring Redlands, about 7 miles from the shooting at Inland Regional Center.
A black sedan parked outside was also searched.
The home is where officers initially saw a vehicle matching the description of the suspects' SUV in the hours before the final gun battle that killed them. A bomb squad on Wednesday swept the building with robots.
Police didn't immediately say if the suspects -- Syed Rizwan Farook and Tashfeen Malik -- lived at the home. Public records show it is a possible residence of a family member of Farook.
Residents tell KABC-TV Redlands is a "sleepy little town" and expressed shock that the killers might be their neighbors.

Federal authorities say that the two assault rifles and two handguns used in the San Bernardino massacre were all purchased legally in the United States -- two of them by someone who's now under investigation.
Meredith Davis of the Bureau of Alcohol, Tobacco, Firearms & Explosives says investigators are now working to make a connection to the last legal purchaser.
She says all four guns were bought four years ago but she's not saying whether they were purchased out of state or how and when they got into the hands of the two shooters.
Davis says California requires paperwork when guns change hands privately but many other states don't.
She also says the rifles involved were .223-caliber -- powerful enough to pierce the standard protective vest worn by police officers, and some types of ammo can even plow through walls.

The action followed a gunbattle between occupants of an SUV and San Bernardino police not far from the original shooting scene.
