Federico Gondola, 35, is charged with premeditated murder. Investigators say he worked as a handyman for the victims before he killed them.

Roosevelt and Janette Dixon, both in their 70s, were found dead in their Kissimmee home on July 14, but investigators say it appears they were killed several days before.

According to court documents, authorities received information that Gondola was trying to extort the couple for money, and when Mr. Dixon reached for his gun, Gondola grabbed it and shot him and his wife.
