Original story:

Authorities in San Bernardino, California, were searching the Loma Linda University Medical Center after reports of a bomb threat there Tuesday, Los Angeles station KTTV reported in a post published to its verified Twitter account. The alleged threat came just one week after a husband-and-wife duo killed 14 people and injured many more when they opened fire at a Christmas party at the San Bernardino social services center where the husband worked.

Victims of that massacre were treated at the Loma Linda University Medical Center. Authorities had not yet announced whether the bomb threat at the hospital was related to last week's massacre, called a terrorist act because the perpetrators were radicalized Muslim extremists. The threat was called in at 10:30 a.m. local time, and the hospital remained on a "code yellow" level alert, the Fox-affiliate station reported.

A second bomb threat was also being explored at San Bernardino High School nearby, according to Cindy Bachman of the San Bernardino Sheriff's Department, in a tweet posted from her unverified account. Authorities evacuated students at the high school in order to search the premises. Students were evacuated to an athletic field, according to a report from Fox News 11.

The bomb threats came as police and FBI continued their investigation into the Dec. 2 massacre that authorities have tied to Islamic extremism. The killers had long been radicalized, according to information released by the FBI, the New York Times reported Monday. “At first it seemed very black-and-white to us that he changed radically when he met her,” one anonymous official told the New York Times of the male shooter. “But it’s become clear that he was that way before he met her,” he said.
