SAN BERNARDINO, Calif. (AP) — The latest on the mass shooting in San Bernardino, California (all times local):

The wife of the couple blamed in the deadly California shootings pledged allegiance to the Islamic State group and the terror group's leader on Facebook using an alias then deleted the messages before the attacks, a U.S. law enforcement official told The Associated Press on Friday.

The remarkable disclosure about the online activities of Tashfeen Malik provided the first significant details suggesting a motive for her participation with her husband, Syed Farook, in the shootings that killed 14 people and wounded 21. Malik was a Pakistani woman who came to the U.S. in 2014 on a fiancee visa before Farook married her in California.

Specifics details about her postings were not disclosed by the law enforcement official, who spoke on condition of anonymity because this person was not allowed to discuss an ongoing investigation.

In addition, the brother-in-law of one of the attackers in San Bernardino, California, says Syed Farook was a 'bad person,' but he wasn't radical.

Farhan Khan also told NBC News he is beginning the legal process to adopt Farook's 6-month-old daughter, who was dropped off with relatives Wednesday morning before the shooting that left 14 dead. Farook and his wife, Tashfeen Malik, were killed in a shootout with police following their deadly rampage.

In excerpts of the interview released Friday, Khan expressed disbelief that Farook would leave behind his infant girl and said he was angry with Farook for the attack.

UPDATE @ 8:00 AM (DEC. 3): SAN BERNARDINO, Calif. (AP) — Authorities are trying to determine a motive for Wednesday's deadly shootings in San Bernardino, California, which could include workplace violence or terrorism.

Police say a heavily armed man and woman dressed for battle opened fire on a holiday banquet for his co-workers. They killed 14 people and seriously wounding more than a dozen others in a precision assault. Hours later, they died in a shootout with officers.

Wednesday's shooting happened at a social services center for the disabled.

San Bernardino Police Chief Jarrod Burguan identified one dead suspect as 28-year-old Syed Rizwan Farook, the other as Tashfeen Malik, 27, his wife or fiancee.

The U.S.-born Farook was a restaurant inspector for the health department. The couple had reportedly dropped off their 6-month-old daughter with relatives Wednesday morning, saying they had a doctor's appointment. The husband of Farook's sister told reporters he last spoke to his brother-in-law about a week ago. He said he was in shock, condemned the violence, and had "absolutely no idea why he would do this."

Federal authorities said the two assault rifles and two handguns used in the violence were purchased legally, but they haven't said how and when they got into the hands of the two shooters.

Also:

  • 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.
  • 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.
