SAN BERNARDINO, Calif. (MEDIA GENERAL) – Information continues to unfold about what happened Wednesday when a husband and wife stormed into a social services center for the disabled in San Bernardino, California and killed 14 people. It was the deadliest shooting in the U.S. since the Sandy Hook elementary school shooting in 2012.

Here's a look at what we know for certain, by the numbers:

14, 21

Fourteen is the number of people killed in the rampage. Twenty-one is the number of people injured. On Thursday, one day after the shootings, we learned the names of all 14 victims.

One of those killed was Nicholas Thalasinos, 52, a man who recently renewed his wedding vows with his wife, Jennifer. Just two weeks ago, Nicholas, who identified himself as a Messianic Jew, was having a heated on-the-job discussion about the nature of Islam with Syed Rizwan Farook, his fellow restaurant inspector and one of the shooters. At the time, co-workers who heard some of the discussion did not sense violence.

Of the injured, 10 were hospitalized in critical condition, and three were in serious condition. Others had been treated and released.

28, 27

These are the ages of the suspected shooters who are both now dead. The suspects, Syed Farook, 28, and Tashfeen Malik, 27, were wearing assault-style clothing when they entered the southern-most building of the Inland Regional Center.

They carried out the attack after dropping off their six-month-old daughter at a family member's house but their motive remains unknown. Family said the couple told them they had a doctor's appointment.

65-75

This is the number of assault-style rounds fired from rifles by Farook and Tashfeen at the public health workers gathered for a holiday banquet.

When asked if anyone was targeted, San Bernardino Police Chief Jarrod Burguan said it was unlikely, "They sprayed the room with bullets."

1,609

This is the number of ammunition rounds found on the suspects in their SUV after a chase and shootout that ended with their deaths.

Four hours after the shooting, officers chased the suspects in their rented SUV. Twenty-three officers from seven different agencies fired approximately 380 rounds at the suspects. Police said the suspects fired 76 rounds back. After the bullets stopped flying, 1,400 rifle caliber rounds and 209 9mm handgun rounds were found on the suspects or in their SUV.

2

Two officers were injured in the melee. One suffered a gunshot wound to the left leg but was expected to be released from the hospital Thursday. Another sustained cuts to his leg.

12

This is the number of pipe bombs authorities found in a town home in Redlands, California.

After the death of the suspects, a bomb squad swept the home with robots and Thursday morning, a black sedan parked outside the home was also searched. In total, the search yielded 12 pipe bombs, hundreds of tools and bomb making materials in addition to 2,000 9mm rounds, 2,500 rifle rounds, and several hundred long rifle rounds.
