MSNBC and CNN aired the footage live as they searched the apartment where Syed Rizwan Farook, a 28-year-old US citizen, and Tashfeen Malik, his 27-year-old wife, had lived.

The couple carried out an attack in San Bernardino earlier this week at the Inland Regional Center, killing 14 people and wounding at least 21 others. They died in a shootout with police late Wednesday.

MSNBC showed on air a driver's license, Social Security card, and other identification documents found in the apartment, among other items.

Los Angeles Times reporter Kate Mather described the apartment as "sparsely furnished" with a "baby crib, toys, and boxes of diapers scattered around."
