23-year-old Sonia Blanco and 25-year-old Evelyn Cruz are not alone.

Not only will their deaths forever be connected - both women killed on Feb. 4, 19-93, their bodies beaten and severely bruised, both strangled to death and dumped to the curb from a vehicle - but they're among a half a dozen or so women all killed in similar fashion over a five-year period in Worcester.

Each victim violently strangled and each murder unsolved.
