LOMITA (KTLA) -- Lomita restauranteur David Viens charged with the suspected death of his wife was moved to a hospital jail ward, detectives said Sunday.

Viens, 47, was transferred to County-USC Medical Center Sunday, which has jail services. He is recovering from a February suicide attempt.

He was charged Thursday with first-degree murder of his wife, Dawn Viens. His arraignment date has not been set, prosecutors said.

Detectives say Viens confessed to the murder from his hospital bed at County Harbor-UCLA in Torrance on Monday.

Meantime, after two days of excavations, investigators have still not located the body of Dawn Viens.

Lomita Sheriffs released a statement Wednesday saying that a search of Viens' husband's restaurant, Thyme Contemporary Cafe on the 24400 block of Narbonne Avenue, came up inconclusive.

The 39-year-old woman was last seen leaving the restaurant before vanishing in October 2009.

Her husband closed the restaurant a short time later for renovations and poured concrete inside the eatery, Los Angeles County sheriff's Lt. Dave Coleman said.

Viens, has long been a considered a suspect in his wife's disappearance, jumped off a cliff in Rancho Palos Verdes on Feb. 23 and sustained critical injuries.

He was arrested Friday and deputies were posted outside his room.

Viens initially told investigators that on the day his wife disappeared, the two had argued and that Dawn walked out.

Investigators searching his former home on Oak Avenue found blood spatter on the walls and are conducting DNA tests to determine if it belongs to Dawn Viens.

According to a report in the Daily Breeze, David Viens told friends that he told his wife to leave their home when she refused to go into rehab.

He said that he blamed their martial problems on alcohol and drugs.
