Lisa Summers Cold Case: DNA Solves 1990 Cornfield Murder

The Tragic Murder of Lisa Summers

• 📌 In 1990, 18-year-old Lisa Summers, a responsible and caring daughter supporting her ailing mother, was found murdered in a cornfield after leaving a friend's house.
• 💔 Her body showed signs of sexual assault, and initial forensic clues were scarce, leaving her family and community devastated.
• 💡 Detective Earl Cooper spent 11 and a half years on the case, retiring with regret as he couldn't bring Lisa's killer to justice.

Early Leads and False Paths

• 🔍 The initial investigation included interviewing the two men who found the body and clearing a coworker's death threat against Lisa.
• 🚶‍♀️ Witnesses reported seeing Lisa with a limping man, identified as David Ashworth, near the crime scene, but his wife provided an alibi.
• ⚠️ Jailhouse informants claimed another inmate confessed, but their stories were inconsistent, revealing they were seeking a deal rather than providing truth.

Reopening the Cold Case

• 🔬 Years later, Detective Bill Rogers reopened the case, leveraging advancements in DNA technology that were unavailable during the original investigation.
• 💬 A new witness, Charlotte Leadbetter, came forward, detailing David Ashworth's suspicious behavior and injuries the morning after the murder, contradicting his initial alibi.
• 🗣️ Ashworth's ex-wife later admitted she lied about his alibi out of fear, confirming he returned home hours after the murder.

DNA Breakthrough and Conviction

• 🧬 Detective Rogers resubmitted crucial evidence, including Lisa's bra and a cigarette butt, for modern DNA testing.
• ✅ The new tests provided a definitive DNA match to David Ashworth, linking his blood to Lisa's bra and the cigarette butt found at the scene.
• ⚖️ Ashworth was tracked to Florida, and despite his denials, the overwhelming DNA evidence led to his conviction in 2008, sentencing him to 60 years in prison.

Lasting Impact and Justice

• 🕊️ Lisa's mother, Dorothy, passed away before seeing justice, a fact that deeply affected investigators and friends.
• 🫂 The resolution brought a form of closure for Lisa's friends, Billy and Julie, who continued to honor her memory and mourn the loss of their "third musketeer."
• 🌟 The case highlights the importance of persistence in cold case investigations and the transformative power of evolving forensic science.
