On November 15, 2008, Jacob Zweig, 17 years old, was fatally stabbed by a classmate, Matthew Carpenter, also 17, in Boca Raton, Florida. During a 15-second altercation, Matthew Carpenter stabbed Jacob four times with a concealed “Scarab” – a quick deployment, out-the-front, double-edged stiletto knife designed for close-combat and the preferred combat-ready knife carried by Navy Seals - the mere possession of which is a crime. The autopsy report showed that Jacob also received in excess of eight defense wounds from the knife. Matthew Carpenter walked away without a scratch on him.
Jacob was unarmed.
Within a few hours of Jacob’s murder and in the dark of the night, Boca Raton Police Detective Juan Pijuan classified it as “self-defense,” despite independent witness testimony, forensic evidence and the killer’s confession, showing Jacob’s killing was premeditated, the result of a drug deal gone bad. Even with this knowledge, Detective Juan Pijuan allowed Matthew Carpenter and his friend to go home that same night along with their cell phones containing incriminating evidence which Detective Pijuan reviewed that night and which contradicted his conclusion of self-defense and further evidenced that Matthew Carpenter was a drug dealer. Detective Pijuan also ignored witness testimony that Matthew Carpenter threatened and stalked Jacob during the two weeks leading up to Jacob’s murder. Matthew Carpenter was also never charged for carrying the concealed weapon. The phones were never retrieved by Detective Pijuan.
Joseph Matthews, a cold-case homicide analyst who has conducted more than one-thousand death investigations, and was credited for solving the abduction and murder of Adam Walsh, together with police internal affairs specialist, Patrick Franklin and the Zweig Family’s attorneys, Senator Walter (Skip) Campbell, Holly Krulik and Karen Sullivan uncovered evidence that Detective Pijuan prepared a homicide report filled with lies and omissions and presented it to the Palm Beach County State Attorney’s Office, resulting in the cover up of Jacob’s murder.
On August 20, 2012, Joseph Matthews and Patrick Franklin filed a formal internal affairs complaint against Detective Pijuan with Boca Raton Police Chief Daniel Alexander. Chief Alexander, however, never sent the complaint outside of the BRPD for an independent review and failed to open an internal affairs investigation against Detective Pijuan who in 2009 received a “commendation” from the BRPD for his handling of Jacob Zweig’s homicide and was promoted to Sergeant.
