Friends say Sierra Clayborn, 27, of Moreno Valley, Calif., a graduate of University of California, Riverside, stood out as someone who always had an encouraging word.
Timothy J. Lee remembered meeting Clayborn in a hip-hop class at college. She was active and outgoing, praising classmates when they mastered a routine. "She always had something encouraging to say," Lee said.
After graduating in 2010, Clayborn worked jobs in retail and at a bank before landing a position at the San Bernardino County Department of Public Health. Like a number of other victims, she inspected restaurants.
Matthew Peairs, 27, a manager at Red Baron Pizza in Big Bear Lake, California, said Clayborn visited the restaurant a day before the shooting to complete an inspection. "She was one of the nicest health inspectors that we've ever had," he said. "She talked to us like normal people, not just doing her job."
He said they discussed their holiday plans and she mentioned she was going to the department's Christmas party Wednesday. "She was stoked about the party," Peairs said.
