A terminally ill cancer patient was arrested and charged with attempted murder after he traveled to the San Francisco Bay Area to kill three doctors who had treated him, authorities say. Yue Chen, who also planned to kill himself, was angry the doctors had treated him like a "laboratory monkey," according to a suicide note found by police, the Mercury News reports. The 58-year-old's family reported him missing on May 31 and responding officers found evidence of the plot at his Visalia home. They then alerted the doctors and Bay Area officials. The names of the hospitals where Chen was treated were redacted in the police report, but prosecutors say one of the doctors worked at UCSF Medical Center.
Chen failed to find any of the doctors, got lost, and may have been on his way back home when he was arrested in San Jose later that day by the California Highway Patrol, the Palo Alto Police Department says. Officials found two loaded handguns in his car, as well as maps with directions to the doctors' homes. After his arrest, Chen told detectives he believed he was being used for research purposes, the AP reports. "They only hurt me," he said. "They hurt me both hospitals. They really screw my life, or the doctors lie to me. Hospitals, they all cover for each other." Chen was charged in Santa Clara County with three felony counts of premeditated attempted murder.
