FONTANA, Calif. (KTLA) — Coroner’s officials have confirmed that a body found five days ago is in fact that of missing Fontana woman Lorna Lopez.

The body was found last Thursday afternoon in a field in the 17300 block of Cucamonga Road.

San Bernardino County coroner’s officials positively identified Lopez, 40, on Tuesday. However, they did not specify her cause of death.

Her estranged husband, Victor Manuel Lopez, 40, was arrested last Thursday on suspicion of murder after he led police to his wife’s remains.

He pleaded not guilty on Monday to the murder charge. A preliminary hearing is tentatively set for March 28.

Lorna and Victor Lopez were both reported missing last Wednesday.

Their three children told authorities that they had not seen their parents since 7 a.m. on Tuesday at their Fontana home as they got ready for school.

Victor Lopez was photographed three hours later at an ATM. There was no sign of his wife.

Lorna Lopez had apparently told her husband recently that she planned to seek a divorce.

Police arrested Victor Lopez’s nephew, 37-year-old Joseph Rodriguez, of Huntington Park, on Thursday morning on suspicion of being an accessory to a felony.

Detectives searched his home and seized evidence that led them to believe foul play might have been involved in Lorna Lopez’s disappearance.

Victor Lopez was arrested after he turned himself in on Thursday. He had been at his parents’ home in Huntington Park.

His parents told investigators that he had seen reports on TV and wanted to surrender to authorities.

The couple had been married 20 years, but had not been living together as a married couple for the past six years.

Their three children range in age from 8 to 18 years old.

Anyone with information is asked to contact the Fontana Police Department at (909) 350-7700.
