Personality:
The first things that come to mind when describing Megan Hunt are that she is driven, a workaholic, passionate about justice, and one of the best at what she does.
As a medical examiner for the Philadelphia police department, Megan is committed to respecting the dead. She believes that her work honors them and makes an effort to find out as much as she can about how they lived. If there's foul play involved, she will stop at nothing to make sure that whoever killed them is brought to justice so their families can have closure. This is a product of her days as a neurosurgeon, when she was so absorbed in the procedures and so detached from who she was working on that she cared nothing for the patients.
She is a workaholic and has no trouble bossing everyone at her job around to get results, even if they are her superiors, caring nothing for how much various tests and procedures cost, as long as it helps her find the answers. Her co-workers describe her as a control freak, which is quite an apt description.
However, though she presents a facade of professionalism and acts like she doesn't care, inside, Megan is very vulnerable. She was in a horrible car accident years before the series began that left her with an undiagnosible condition that makes her hands shake and go numb (though it's implied that it's psychosomatic). The condition led to her accidentally killing a patient on the table, ending her promising career as a neurosurgeon. The patient's death haunts her to this day.
Megan also went through a messy divorce from her ex-husband, Todd, and lost custody of her daughter, Lacey. Todd presented Megan as a bad mother who wanted nothing to do with her daughter's life, an impression Megan is desperate to correct. However, she can be very overzealous and often pushes too hard or tries too hard to be nice and a "cool mom", making Lacey push her away further.
Megan is also very socially-inept; during her career as a neurosurgeon, she made little effort to connect with people, considering the job to be more important. Even now, as a coroner, she tends to keep people at arms' length emotionally, never interacting with them outside a work environment, though she's recently begun trying to change this and open up more.
History: (in progress)
Much about Megan Hunt's early life is unknown. However, when she was very young, she came home from school one day to find a police officer waiting for her. Her father had apparently committed suicide, though as Megan grows older, she becomes convinced that there was something more to it. Her mother wanted her to let it go, however, and Megan's inability to do so led to a strained relationship between the two. Megan was also very close to her father, and his death devastated her, further driving a wedge between mother and daughter.
As she grew, Megan went through medical school and eventually became an accomplished neurosurgeon. She was very good at what she did, but the job also required her to put in long hours, which damaged her marriage to her husband, Todd. Five years before the series began, Todd divorced her. He was granted full custody of their young daughter, Lacey, because as Megan put it, the court believed that her working 18 hours a day made her a bad mother, while his working 18 hours a day made him a good provider. Todd began to paint Megan as the "bad guy", making it seem to Lacey that her mother wanted nothing to do with her.
Around a year after that, Megan was involved in a car accident when she, distracted by arguing with Todd on the phone, drove through an intersection and was T-boned by a semi. She survived, but was left with a condition that left her hands numb and shaking at unpredictable times. She went through batteries of tests and scans, and nobody could find anything wrong with her. Though she tried to press on with her neurosurgery career in spite of it, she ended up killing a patient on the table. The malpractice suit was settled out of court, but Megan realized she couldn't live with it and closed up her practice, instead becoming a coroner for the Philadelphia Police Department, reasoning that she couldn't do much more harm to someone who was already dead.
Eventually, she was paired with Medical Investigator Peter Dunlop, a former cop who survived being shot and decided he liked medicine better than doing the dirty work.
