The Tragic Discovery

On November 20, 1994, a friend made a horrifying discovery at Robin Lawrence’s home. Blood covered the primary bedroom, and Robin’s 2-year-old daughter had been wandering alone for approximately two days. Investigators determined the attack likely occurred on November 18.

Robin, a talented artist and advertising professional, had fought desperately for her life. The intruder entered through a rear window off the deck, cut the phone line, and left evidence of a violent struggle.

The Cold Case Breakthrough

For 29 years, one piece of evidence held the key: a small blood stain on a bathroom washcloth containing DNA that didn’t match family members or anyone in CODIS. With no fingerprints or leads, the case went cold.

Everything changed when forensic genealogy entered the picture. Analysts built family trees using the DNA profile, tracing European ancestry lines until they identified a potential suspect—Stephan Smerk, a former soldier living in upstate New York.

The Stunning Confession

When detectives visited Smerk in September 2023 to request a DNA swab, he called a local police station that same night to turn himself in. His videotaped confession revealed chilling details.

Smerk admitted he was 22, drinking heavily, and taking ephedrine when he randomly decided to kill someone. He described wearing a mask and gloves during the attack, and acknowledged that Robin begged for her life while fighting back. His most disturbing statement: “I am a serial killer who’s only killed once.”

Justice After Three Decades

Smerk pleaded guilty to first-degree murder and received a 70-year sentence. While he may be eligible for parole in 2037, the family finally has answers after nearly 30 years of unanswered questions.

Robin’s legacy extends beyond this tragedy—she created artwork connected to a civil rights medal and is remembered for her artistic contributions and vibrant spirit.
