UCSF Urinary-Tract Researcher Accused of Poisoning Colleague

Benchun Liu, 38, a post-doctoral fellow at the University of California at San Francisco in the urology department, was arrested on Friday for attempted murder. His victim? Mei Cao, who works as a lab research associate in the same department. Liu, a Chinese citizen, has since put on immigration hold and is still in custody at SF county jail. Cao, however, after a brief stint in the hospital, is doing just fine. (CBS 5)
