Anthony Shea, an 18-year veteran of the sheriff’s office, resigned from his post as sergeant in August in the middle of an investigation into accusations that would have resulted in his firing, according to the sheriff’s office and an arrest affidavit.

Eloilda Shea, a 39-year-old Lt. at the Orange County Sherrif's Office, was allegedly murdered by her estranged husband, former Sgt. Anthony Shea, 49, on Friday.

The Sheriff’s Office on Friday afternoon announced Anthony Shea — a 49-year-old sergeant who quit during an internal investigation of an on-duty affair — was in custody days after Lt. Eloilda Shea, 39, was reported dead at their family home on El Prado Avenue.
