Linda Faye Sutherlin, 21, was killed on November 4, 1971, in Brazoria County, Texas. Her death was investigated as part of a wider probe into the deaths of six women across Montgomery, Harris and Brazoria counties.

Anthony Michael Knoppa was arrested and convicted in connection with Sutherlin’s murder; in 1972 he received a 50-year prison sentence. Harry Andrew Lanham was also implicated and sentenced to 25 years, but he was later shot and killed by an officer in the Harris County Jail when he attempted to grab the officer’s gun. Prior to Sutherlin’s murder, Knoppa had a prior conviction in a rape case and had once pleaded to a lesser charge after a victim was fearful of testifying.

Anyone who knew Linda Sutherlin or has information about the broader series of deaths is asked to share what they know.
