HOBE SOUND, Fla. — The ex-husband of a missing Florida woman has been arrested on second-degree murder and child neglect charges.

During a news conference Wednesday morning, Martin County Sheriff William Snyder said 30-year-old Steven Williams confessed to killing Tricia Todd in April. The Air Force airman was arrested Tuesday in North Carolina.

She was last seen at a Publix supermarket on April 26 and reported missing the next day.

Snyder wouldn't say how Todd died. Her body hasn't been found, but Snyder says officials are redoubling their efforts to find her remains.

The sheriff's says the lack of a body won't stand in the way of prosecution.

Snyder says Todd's 2-year-old daughter was there when her mother was killed. She is now living with family members.

Williams is being held without bond and records don't indicate whether he has a lawyer.
