The crime-fighting show "America's Most Wanted" will once again profile the Thanksgiving night massacre in Jupiter that left four family members dead and one of their relatives on the run.
The show will focus on the international manhunt for Paul Mehrige, in partnership with the Jupiter Police and the US Marshals Service.
Host John Walsh has a news conference scheduled for Tuesday afternoon on Miami Beach where he'll be joined by Jim Sitton, the father of the 6-year-old girl who was killed in the shootings. Officials from the Jupiter Police Dept. and US Marshal's Office will also be there.
Federal authorities have already unveiled billboards with a picture of Merhige in South Florida — one on southbound Interstate 95 in the Delray Beach area and the second in the Hallandale Beach area, just north of the Miami-Dade County line.
Merhige, 35, is wanted on four counts of first-degree murder charges in the deaths of his 6-year-old cousin, 79-year-old aunt and twin sisters after Thanksgiving dinner in Jupiter.
Merhige has a history of mental instability and took medication for depression and anxiety. A law enforcement source has told CBS4 News the suspect had previously attempted suicide, but U.S. Marshal's appear convinced Merhige is still alive and on the run.
Investigators have previously released ATM photos of Merhige withdrawing large amounts of cash before the murders, part of what they believe was a pre-conceived plan to be able to maneuver without leaving a trail of electronic transactions.
He may be driving a royal blue 4-door Toyota Camry. There is a $100,000 reward for information leading to his capture.
