Does Worcester have a serial killer?
That's what residents were asking Worcester Police in early 1993.
From December 1992 to February 1993, four women were killed. They had all been strangled to death.
On Feb. 4, 1993, the bodies of 23-year-old Sonia Blanco and 25-year-old Evelyn Cruz were discovered just a few miles apart and within 20 minutes of each other.
30 years later, the murders of Sonia Blanco and Evelyn Cruz remain unsolved.
