Linda Faye Sutherlin, a 21-year-old woman, was tragically killed on November 4, 1971, in Brazoria County, Texas. Her death was the result of a brutal murder, in which she suffered 72 bullet wounds to her back, shoulders, and legs. The case was part of a larger investigation into the deaths of six women in Montgomery, Harris, and Brazoria counties, though only one conviction was secured in connection with Sutherlin's murder.
Authorities arrested and convicted Anthony Michael Knoppa for
the crime. In 1972, Knoppa was sentenced to 50 years in prison for the murder of Sutherlin. Another individual, Harry Andrew Lanham, was also implicated in the killing and sentenced to 25 years in prison. However, Lanham was later shot and killed by an officer in the Harris County Jail when he attempted to grab the officer's gun, eliminating a key witness in the case against Knoppa. This incident weakened the prosecution's ability to pursue charges against Knoppa for the other five deaths under investigation.
Prior to Sutherlin's murder, Knoppa had been convicted in a rape case. Testimony during his trial revealed that he had taken a young woman to an auto salvage yard and repeatedly assaulted her. Due to the victim's fear of testifying, Knoppa pleaded guilty to a lesser charge. His history of violent crimes and threats against law enforcement raised concerns when he was released from prison after serving only 15 years of his sentence. Authorities feared that he would seek revenge against law enforcement officers in the Houston area.
The murder of Linda Faye Sutherlin remains a tragic chapter in the history of violent crimes in Texas. Her case was part of a broader investigation into multiple homicides, but the full extent of Knoppa's involvement in other crimes was never fully prosecuted due to the loss of key testimony.
