Julian Ospina Florez, who worked for the wife of a wealthy Tampa couple found dead Monday, is expected to face a judge Wednesday in connection with the shocking murders.

Florez, 31, was arrested on two counts of first-degree murder, Hillsborough Sheriff David Gee said Tuesday, calling the nature of the deaths "very brutal" as both Dr. Hector Rivera, 76, and his wife Debra, 55, had been shot multiple times.

Florez, of Tampa, was booked late Tuesday into Hillsborough County Jail. He was Debra's assistant and driver, police said, adding the relationship had gone sour as Debra had "become distrustful" of him after some of her jewelry vanished. The pair reportedly got into an argument Monday after he drove Debra to fulfill a business obligation in Sarasota.
