Retired agent Lance Leising served in the FBI for nearly 23 years.
In this episode of FBI Retired Case File Review, he reviews his FBI Ten Most Wanted fugitive investigation of Jason Derek Brown.
Jason Brown is wanted for the execution-style murder and armed robbery of Keith Palomares, a 24-year-old armored car guard, carrying the weekend deposits of a movie theater in Phoenix, Arizona in November 2004. Brown fled with the money and is still at large. The FBI is offering a reward for up to $200,000 for information leading directly to the arrest of Jason Brown. Thank you to the Phoenix Division and current case agents for allowing Lance to speak with me about this active fugitive investigation.
Jami Brown Martin, Jason Brown’s sister, is also a guest on this episode.
Jami, who lives every day with the horrible truth and many consequences of his brutal act, provides her personal insights about her brother, his actions immediately following the murder, and why she’s cooperating with the FBI in the efforts to locate and apprehend him.
