Sabrina Blackshear, 45, of Jacksonville, Florida, was found dead on Silver Street on May 20, 2015, with a gunshot wound to the chest. Investigators recovered a .40 caliber shell casing and a used condom at the scene; both items were submitted to the Florida Department of Law Enforcement for analysis. The case remained unsolved for more than two years.

In August 2017, DNA and cellphone records led to the arrest of Troy Allen Butler, a convicted felon. Butler had reported his car stolen in August 2015; that vehicle was later tied to a separate St. Augustine murder. A firearm recovered from the stolen car matched the shell casing from Blackshear’s scene, and DNA from the used condom linked Butler to the crime. Butler acknowledged meeting Blackshear for prostitution but denied killing her, while cellphone data placed him near Silver Street the night of the murder.

Anyone with information about Sabrina, her activities that night, or who may have seen a vehicle linked to this case around May 20, 2015, is asked to come forward.
