Postdoc Arrested

A postdoc at the University of Maryland School of Medicine is facing drug charges after the death of his girlfriend, who was also a postdoc, the Associated Press reports. Carrie Johns, who studied the effect of drug use on the brain, died after injecting herself with buprenorphine, a narcotic used to treat heroin addicts. Johns had trouble breathing and was pronounced dead at the university emergency room. According to WBAL in Baltimore, McCracken told the police that he purchased several drugs from the Philippines over the Internet and that both of them were planning on using them.

Blogger DrugMonkey goes into more detail and says that this hit "close to home." He also adds, "I have a thought for all of their colleagues who might be casting about for answers — it is not your fault for not noticing."
