SAN BERNARDINO, Calif. (AP) — In the chaotic aftermath of the San Bernardino shootings, as the wounded bled from gunshots, others lay dead and police searched for multiple killers, an officer relayed the name of a suspect to dispatchers.

 The officer identified Syed Rizwan Farook, a co-worker of most of those shot, as a possible suspect because he had left a work meeting "out of the blue" 20 minutes before the shooting and matched the description of a gunman, according to audio of dispatch recordings. 
 
 "He seemed nervous," the unnamed officer reported in an edited selection of recordings posted by The Press-Enterprise newspaper of Riverside. 
 
 Farook and his wife carried out the attack that killed 14 people and wounded 21 others Wednesday. The couple, who the FBI said had become radicalized, died about four hours later in a firefight with officers in this city an hour east of Los Angeles. 
 
 The shooting occurred at the Inland Regional Center, a social services agency, where the county Department of Public Health was renting the auditorium for an annual meeting. 
 
 Trudy Raymundo, director of the department, was preparing to make a presentation when she heard gunfire outside. A gunman in a black ski mask and dressed all in black then burst through the door and started shooting. 
 
 Raymundo dropped to the floor and huddled under a table with other colleagues as bullets sprayed the room that had been decked out with a Christmas tree, ornaments and other seasonal decor. 
 
 "It's constant shots and constant firing, and all you can think of is, 'Why don't they stop?'" Raymundo said Monday in her first public comments since the slaughter. "It was just endless." 
 
 County health employees had trained for an active-shooter scenario a year earlier in the same room. 
 
 "Everyone was trying to be quiet and not draw attention to themselves as they were trained to do, to try to find as much protection as you can," said Corwin Porter, assistant director of the department. "Unfortunately the room just didn't provide a whole lot of protection." 
 
 Family members of witnesses said the initial gunfire lasted about 30 seconds and then the shooters reloaded and fired again before fleeing without saying a word. 
 
 Raymundo said she saw one man enter the room, but that two left. 
 
 Dispatch recordings reveal the back-and-forth from officers in the field and calm-talking dispatchers, including some of the confusion and misinformation that was relayed as they tried to figure out how many suspects were involved and whether they were still at the Inland Regional Center. 
 
 "We do not know if we still have an active shooter," one of the first officers on the scene reported. "We supposedly have two down inside. We'll be making entry." 
 
 A dispatcher put out the call: "San Bernardino Police Department has an active shooter. ... They're asking for all units that are available." 
 
 Nearly six minutes into the recordings, an officer identifying himself as Ida 9 reported Farook's name. 
 
 He said the suspect "left out of the blue and, um, then 20 minutes later the shooting occurred." 
 
 Witnesses reported seeing a pair of gunmen wearing ski-type masks and vests, an officer said. 
 
 A dispatcher later advised all units that three suspects wearing black masks and, possibly, tactical vests, fled in a black SUV with assault rifles. 
 
 At some point, a man's voice reported a dozen "DOAs," using the jargon for dead on arrival, and said others had been moved to a treatment area. 
 
 That is followed by chatter about a bomb that shooters left behind. 
 
 A lieutenant then tells all sheriff's deputies and police officers to get out of the building. 
 
 "Bomb arson has seen the device," someone said. "It is out of the norms. They are going to explode it through robotic means. They have pulled out of the building as well." 
 
 The recordings pick up about four hours later as a short chase ends in a shootout between the couple and nearly two dozen officers. 
 
 Shots were being fired out the back window of the SUV, and a dispatcher reported that officers were taking fire. 
 
 A helicopter pilot reported that his partner was moving to the backseat of the chopper, armed with an M4 rifle. 
 
 Gunfire can be heard in the transmissions. 
 
 "Can see one guy down," an officer reported. "There's one guy in the back of a car." 
 
 In the background, a man can be heard yelling, "Hold your fire, hold your fire." 
 
 Police later said the couple fired off 76 rounds in the shootout, but the two were outgunned by officers, who shot 380 rounds. ||||| (CNN) Investigators believe San Bernardino shooter Syed Rizwan Farook may have been plotting an earlier attack in California with someone else, two U.S. officials said. 
 
 One of the officials said the two conspired in 2012 and a specific target was considered. Neither of the officials could say how serious the plotting got.

 "They got spooked," the official said.

 San Bernardino terror couple Syed Rizwan Farook and Tashfeen Malik spent at least a year preparing for their terror attack, NBC News has learned, practicing at a local gun range and making financial plans for their family after their deaths. 
 
 And the husband may have discussed an attack as many as three years ago, law enforcement sources said Tuesday. 
 
 Two sources said Farook and Malik had practiced their shooting skills at a Riverside, California-area gun range for a year or more before last Wednesday’s attack on a holiday office party. They killed 14 people and wounded 21 more with firearms at the Inland Regional Center in San Bernardino. 
 
 Counterterrorism officials also told NBC News that Farook and Malik were making preparations for some time to “take care of both grandma and the baby.” The couple lived in a Redlands, California residence with their 6-month-old daughter and Farook’s 62-year-old mother, Rafia Farook. They left their daughter with Rafia Farook on the morning of the attack. 
 
 Investigators are examining a $28,500 deposit made to Farook’s bank account in the weeks before the Dec. 2 rampage. 
 
 A U.S. counterterrorism official said that he didn’t have details on the transfer, but that it “would be consistent with them making preparations for grandma and the kid.” 
 
 “They had purposely thought through that problem,” said the official. “There were other indications of preparations.” 
 
 Reuters reported that the loan to Farook was made by the online lender Prosper. In a statement, Prosper said that the company is "prohibited by law from disclosing any non-public, personally identifiable information regarding any loan originated through our platform." 
 
 "All loans originated through the Prosper platform are subject to all identity verification and screening procedures required by law, including U.S. anti-terrorism and anti-money laundering laws," the spokesperson said. "Like all Americans, Prosper is shocked and saddened by recent events in San Bernardino." 
 
 And a senior law enforcement official told NBC News Tuesday that FBI investigators have been told that Farook discussed staging an attack in California as early as 2012. 
 
 The official said investigators don’t yet know what to make of the claim, although they say it may bolster their growing suspicion that Farook was radicalized long before he returned from Saudi Arabia last year with his wife. 
 
 The latest revelations come after NBC News reported Monday that federal investigators are interviewing a neighbor of Farook and Malik who bought two of the four guns that were used in the massacre. ||||| The loan offers investigators a key new detail as they try to unravel how Syed Rizwan Farook and Tashfeen Malik plotted the deadliest terrorist attack on U.S. soil since 9/11. The money could also explain how they managed to pay for target practice at local gun ranges, as well as the rental sport utility vehicle they used during the Dec. 2 attack, the officials said.
– San Bernardino shooter Syed Rizwan Farook may have been planning mass murder even before he married accomplice Tashfeen Malik, according to sources close to the investigation. Officials tell CNN that Farook plotted to carry out an attack with somebody else in California in 2012, though it's not clear how far the preparations went. The plan was called off after a round of terror-related arrests in the area "spooked" Farook and his accomplice, one source says. Law enforcement officials tell NBC News that Farook and Malik appeared to have planned the San Bernardino attack for at least a year, training at local gun ranges and making financial arrangements for their 6-month-old daughter and Farook's mother. The FBI is still investigating a loan of $28,500 deposited into Farook's account two weeks before the attack, a loan that an investigator tells NBC "would be consistent with them making preparations for Grandma and the kid." In other developments: The Los Angeles Times reports that former Minneapolis resident Mohamed Abdullahi Hassan, an alleged ISIS recruiter who targeted Westerners on social media, has surrendered to authorities in Somalia. Investigators suspect he may have influenced Farook. The San Bernardino Department of Public Health, which employed Farook and most of the 14 people killed in the attack, trained employees last year for an active-shooter drill in the same room at the Inland Regional Center that Farook and Malik attacked, the AP reports. "Everyone was trying to be quiet and not draw attention to themselves as they were trained to do, to try to find as much protection as you can," an assistant director of the department says. "Unfortunately, the room just didn't provide a whole lot of protection." Law enforcement sources tell the Times that a device Farook and Malik left behind at the scene of the attack may have been designed to kill first responders. The sources say the crude device, which included three pipe bombs, was disabled by water from the building's sprinkler system. See a photo of the holiday party taken just before the shooting here.
