The ex-husband of a missing Florida Air Force veteran has been arrested and charged with her murder, the Martin County Sheriff's Office announced Wednesday.
Air Force airman Steven Williams, 30, is facing second-degree murder and child neglect charges. Williams has been ordered held without bond and court records don't indicate whether he has hired an attorney.
At a news conference Wednesday morning, Martin County Sheriff William Snyder said Williams confessed to killing 30-year-old Tricia Todd — a mother and hospice nurse — and disposing of her body in a wooded area near Jonathan Dickinson State Park.
Todd's body hasn't been found. Snyder said Wednesday crews were searching a 15-mile wide area, redoubling their efforts to find her remains.
Todd was last seen at a Publix grocery store in Martin County on April 27 prompting a large-scale, multi-agency search, NBC affiliate WPTV reported.
Officials said Todd was killed the night of her disappearance and that her 3-year-old child was nearby when she was killed. He had no accomplices in the killing or in disposing of the body, officials said.
Williams had been cooperating with authorities and even agreed to a polygraph test on May 3.
"Nothing in (William's) lengthy interview — and it was a long and detailed interview — nor his polygraph exam indicated that he was involved or had any additional information about Tricia Todd's disappearance," Snyder previously said.
He was also interviewed by a lieutenant, two detectives and an assistant state attorney in North Carolina, where he was stationed at an Air Force base.
Williams was seen on camera buying gas at around 1 a.m. on the day Todd went missing, later telling investigators that she asked him for it because the fuel in her car was running low, NBC News reported.
Officials said Williams was taken into custody Tuesday in North Carolina and was brought back to Martin County.
Williams had been assigned as a field training detachment instructor with the Air Force's 372nd Training Squadron. The Air Force said in a written statement Wednesday they are "cooperating fully with civil authorities in this case."
