A Queens couple charged with burglarizing at least 19 Nassau homes this year was arraigned Wednesday, Nassau prosecutors said.

Jorge Guevara, 36, of 56th Road in Bayside, who allegedly broke in through back doors and windows, was held without bail in connection with 20 counts of second-degree burglary, three counts of second-degree attempted burglary and one count of third-degree burglary, officials said.

Johana Gomez, 38, of 34th Street in Astoria, who allegedly knocked on doors to make sure no one was home, was held pending a $1.1 million bail in connection with 19 counts of second-degree burglary, three counts of second-degree attempted burglary and one count of third-degree burglary, officials said.

Both were represented by Legal Aid, which does not comment on cases.

Police believe the two are responsible for at least 34 Nassau break-ins since January and may also have burglarized homes in New York City and New Jersey.

Guevara and Gomez were under police surveillance Monday when they tried to break into a Merrick home and were arrested, Nassau police said.

Investigators at first thought they had three sets of burglars, but then a Second Precinct sergeant on a burglary case honed in on a maroon Nissan Altima seen near the scene, police said. It had a license plate that was similar to a white Mercedes caught on video near two or three burglaries, and using the department’s network of license plate readers, investigators realized the same plate was being used on different cars.

When the couple was arrested, they were driving a Lexus with the same plate that had been attached to the Mercedes, police said. Detectives seized the Nissan and Lexis but the Mercedes had been sold, officials said.

Jewelry taken from both suspects’ homes may have been from some of the heists, police said, and detectives are trying to return the items to the owners.
