Sources familiar with the case said there is a sealed indictment in New Jersey related to the murder of Yee, and that someone has been arrested in N.J. on non-related charges.
The suspect's name has not been revealed, but the source confirmed the information, which was first posted on a Website for former Miami police officers over two months ago.
A Dec. 17, 2009 update on the Yee case on mpd-vets.org states that "an arrest has been made in New Jersey on a sealed Grand Jury Indictment from Dade County."
Information has been scarce since the July 10, 2009 shooting of Yee, at Miami's Hurricane Cove Marina.
Retired after 25 years on the force, Yee, 61, was working as a security guard at the Marina at 1884 NW North River Drive.
He was found with multiple gun shot wounds to the back of his head and died a short time later at Jackson Memorial Hospital.
Miami police staged a reenactment of the crime and Yee's family made a public plea in the hopes of solving the case and finding Yee's killer.
A sketch of the suspect was later released by police, and a video was posted on YouTube in the hopes of generating leads.
Sources also said Yee's family members are pressuring authorities to have the suspect brought from N.J. to Miami to face the charges.
