Blood droplet leads to arrest of suspect


CostaBoca Raton, FL – Sometimes, it's the smallest piece of evidence that helps solve a crime, such as a tiny drop of blood.  Back on August 6, 2009, Barbara Montelius reported her 2002 Honda Accord was broken into overnight while parked at 1132 SW 4th Street.  Someone used a brick paver to smash through the front passenger door window.  The only property stolen was a plastic bag containing clothes. The bag was recovered the next day.

 While searching through the vehicle for any evidence, Officer Kelly Shifflet noticed a suspected blood spot on the front passenger seat, just below the headrest.  Crime Scene Technician (CST) Frank Katen processed the seat and collected a swab from the stain.  On March 9, 2010,, CST Katen received notice that the DNA sample he submitted matched a sample in the Florida Department of Law Enforcement's (FDLE) database.  The match came back to Anthony Costa. Samples of Costa's DNA were in the system from a 2002 Boca Raton robbery conviction. 

Once located by the Boca Raton Police Special Investigations Unit (SIU), Costa admitted to detectives that he burglarized or tried to burglarize every vehicle he came across in a 10 block radius of 181 SW 11th Court.  Costa subsequently admitted to burglarizing Montelius' car and was charged with Burglary of a Structure or Conveyance and Petit Theft.
