The homes, in Burlington County's Evesham, Medford, Moorestown, and Mount Laurel Townships and the Camden County towns of Haddonfield and Voorhees, "were in upscale neighborhoods, near a golf course or wooded lot with minimal views, and secluded from neighboring properties," according to a release from the Prosecutor's Office.
Gittens and Petit also used a police radio, the Prosecutor's Office said, to listen for news of their possible discovery.
The duo would burglarize the houses when no one was home, a spokesman for the Prosecutor's Office said.
"They would study the patterns," spokesman Joel Bewley said of the residents. "In one case, they were frightened away by a barking dog."
One of the accused burglars left a flashlight behind at a burglarized home, the Prosecutor's Office said, which was the break in the case, as DNA on the flashlight matched a record in the system.
That gave police probable cause to examine phone calls and text messages, Bewley said.
Gittens and Petit were arrested Sept. 5. Police were able to recover more than 500 of the stolen items, the Prosecutor's Office said, including some that were in an abandoned Philadelphia building and others buried in the yards of one of the men's homes.
Both men were released after posting bail. An arraignment has not yet been scheduled.
Gittens was indicted on 22 counts of burglary, 16 counts of theft by unlawful taking, weapons violations, and related charges. Petit was indicted on nine counts of burglary, nine counts of theft by unlawful taking, weapons violations, and related charges. Both were also charged with "possession of a radio to intercept emergency communications while attempting to commit a crime."
The total of 96 counts leaves each facing up to several decades in prison.
