The strangler left his fingerprints on Shannon Marie Weaver’s neck in 1990, but Arlington police have yet to match the prints to a suspect.

Weaver was 23 years old U.S. Navy employee when her boyfriend found her dead in her bedroom around 10:30 p.m., Nov. 30, 1990. Her infant twin sons, unattended in a nearby crib, were unharmed, Arlington police said.
