A 42-year-old man was sentenced Friday in Seattle to 21 years in prison for strangling a woman two years ago at her apartment in the city's Belltown neighborhood.

Gary B. Wade was convicted of murder last month in the death of Michelle Thornton.

KOMO reports (http://is.gd/fRQ1uR) investigators found evidence she had been sexually assaulted.

Prosecutors said Wade has a criminal history in Florida, Georgia, Utah as well as Washington where he was previously convicted of possessing cocaine.
