It's been nine years.

Yet, not a single arrest has ever been made for the Warsaw cold case murder of Sarah Gibbs. The 34-year-old autistic woman was living independently in her Warsaw apartment with Cardinal Services when she was murdered on December 19, 2014.

Warsaw Police Detective Ryan Moore says despite the lack of leads they've gotten up to this point, they are still working vigilantly on the case. 

Howard Gibbs, Sarah's father, says the murder of his daughter is something he and his wife Betty, also think about everyday.

Intially being told their daughter had died in a fire, it would be days later until they found out that her death was more than an accident. An autopsy would later reveal that Sarah had been stabbed to death before the crime scene was set on fire.

Gibbs said the Christmas of 2014 would easily be considered the worst Christmas of his life.  

Although investigators know what happened to Sarah, they still don't know what transpired prior to the crime. One thing her father knows is that Sarah's autism made her an easy target for the murderer. 

The Gibbs family continue to remember Sarah for who she was as a person rather than focus about how her life came to an end. The lack of justice and closure, however, has been hard on the family since Sarah's death. 

Over the years, Gibbs has shared the locations Sarah was known to frequent in Warsaw with local media sources. The family continues to hope that someone may remember an interaction with their daughter that could produce a lead for the case.

Sarah's apartment had been across the street from the Kosciusko County Fairgrounds. Not being able to drive meant Sarah usually stayed close to that area. Gibbs said Sarah was known to frequent places like the Warsaw Community Public Library, stores around Market Street, and the old YMCA. 

Despite nine years passing by with no major leads, Detective Moore said he still isn't giving up hope about catching Sarah's killer. He urges anyone who knows anything about Sarah's murder to contact the Warsaw Police Department.

Michiana Crime Stoppers also has a $10,000 reward that still stands for information that leads to an arrest in Sarah's case.
