The son of a U.S. federal court judge is going on trial in Puerto Rico, charged with the first-degree murder of his wife.

Pablo Casellas Toro appeared in court Wednesday as jury selection began.

Casellas is accused of shooting Carmen Paredes Cintron on July 14 at their home in the upscale San Juan suburb of Guaynabo. He also is charged with destroying evidence, making a false report and weapons violations.

The 47-year-old insurance broker has denied killing his wife, saying he came home to find her dead and an unknown man jumping over a fence. He says he shot at the man but missed.

Casellas is the son of U.S. District Court Judge Salvador Casellas, a former Puerto Rico treasury secretary who was appointed to the federal bench in 1994.
