On this week's episode of True Crime New England, Katie and Liz tell the heartbreaking story of a murder that took place in Kennebunk, Maine. 18-year-old Mary Tanner, known as a free spirit, was entering her senior year of high school. She had just recently found out she was pregnant with her boyfriend of over a year, and was excited about the pregnancy. On a warm July night in 1978, Mary attended a local parade, went bowling, and attended a party. Like she always did, she elected to hitchhike home. When she never arrives, her family is worried. Not even a full two days later, her body is found on Grace Evans Field in Lyman, Maine. She had been brutally beaten, and her body had started to decompose in the July heat. While there was at least one credible suspect, no one was charged in Mary's murder. Over 44 years later, her murder still has not been solved. Anyone with any information on the murder of Mary Tanner is asked to please call the Maine State Police at 207-657-3030.
