It's early in the morning, around 2 a.m. on Tuesday, October 12, 1982.
A crew of Providence & Worcester railroad workers are on the Boston & Maine railroad tracks that run alongside Interstate 290 expressway and Crescent Street in Worcester.
As the workers make their way along the tracks, heading in the direction of Lincoln Square, they discover the naked body of 24-year-old Ethel Bosworh under the expressway overpass at Crescent Street.
Ethel's body was badly beaten and mutilated.
The mother of three young boys had never returned home the night before.
And more than 40 years later, Ethel's murder remains unsolved.
