Family members of a woman killed in the San Bernardino attack are seeking $204 million in damages in three claims against the county.

The father, stepmother and sister of 27-year-old Sierra Clayborn filed claims of negligence and wrongful death against San Bernardino County on Thursday. They also accuse the county of fostering a hostile work environment and failing to provide a safe workplace.

The claims are a precursor to a lawsuit.

County spokesman David Wert said in a statement Friday that "the county will carefully consider each claim and act in the best interests of everyone involved."

Friends described Clayborn as friendly and outgoing, quick to offer an encouraging word and enthused about her work as a health inspector.

The Clayborns are the second family to file claims stemming from the shooting. Earlier this month, the widow of 37-year-old Michael Wetzel filed four claims against the county seeking damages of $58 million for her and the couple's three children.

Clayborn and Wetzel were among 14 people killed in the Dec. 2 shooting, the deadliest attack on U.S. soil since Sept. 11, 2001.

The two shooters — county environmental health specialist Syed Rizwan Farook and his wife, Tashfeen Malik — were killed in a gun battle with police.
