CORAL GABLES, Fla. -

Police on Wednesday arrested a couple accused of robbing his boss' wife of $404,000 in jewelry and cash at her Gables Estates home, then taking off in her Aston Martin.

Police charged 47-year-old Zuhdi Musa and 45-year-old Rosa Maria Musa with armed burglary with assault or battery -- which carries no bond -- and armed grand theft.

On Sept. 26, the pair drove into the Gables Estates in a friend's car and pulled up to 110 Arvida Parkway, according to an arrest affidavit.

"[They] borrowed that car for the sole purpose of committing this robbery," said Coral Gables police spokesman Dean Wellinghoff.

Zuhdi Musa then donned a mask and entered the home.

"He obviously felt very confident and comfortable inside the house," said Wellinghoff. "He knew exactly where he was going in the home."

Once inside, Musa searched two drawers in the master bedroom, then went downstairs and confronted the homeowner, police said. He ordered her to the ground, bound her hand and legs with flex ties, and covered her mouth with tape.

"They taped my hands and they taped my face and then they taped my legs," the homeowner told a 911 dispatcher.

Musa stole the homeowner's diamond necklace and diamond earrings worth $400,000, took $4,000 cash, then stole her Aston Martin, police said. The day after the burglary, the car was found at Southwest 146th Lane and 126th Place.

"Thank God I'm alive," the homeowner told the dispatcher.

Rosa Maria Musa admitted to the robbery after she was arrested, police said.

Zuhdi Musa told a Miami-Dade Circuit Court judge that he worked for the homeowner's medical company for more than a year. Local 10's Christina Vazquez spoke with him the day after the alleged robbery, and he expressed his concern for the victim.

"I think they are very well known to both victims," added Wellinghoff.

"We went to their apartment, very modest apartment in Kendall. Is this a situation of a man who is very close to seeing how the other half lives and wanted to steal his piece of the pie?" Vazquez asked.

"Well, that's a good possibility," replied Wellinghoff. "I never speculate as to somebody's reason for doing something but that -- that may not be far off."
