In November 1994, a New York woman named Robin Warr Lawrence was living in Fairfax County, Virginia, when she was brutally murdered and her young daughter was left to roam the house unattended for days. On Monday, Lawrence’s daughter Nicole, her best friend and her cousin sat in the front row of a press conference where Fairfax County police announced the murderer had been apprehended after nearly 30 years, thanks to evolving DNA-recognizing technology. At the time, the DNA evidence matched none that were in the police department’s database.
