It’s been a week and a half since rebels killed Muammar Gadhafi, after taking his hometown of Sirte. Libya is now a country in the midst of healing old wounds and trying to rebuild a nation.  Dr. Catherine Mullaly, an anesthesiologist with Massachusetts General Hospital, was working in Qasr Ahmed Hospital in Misrata the day Gadhafi was captured and killed. She’s just returned from a six week assignment there with Médecins Sans Frontières, and shares what she saw in the days after Gadhafi’s death.
