The Martin County Sheriff's Office announced Wednesday it has arrested the ex-husband of Tricia Todd, a Hobe Sound woman missing since last month.
Steven Williams, 30, is facing a charge of second-degree murder and child neglect and being held at the Martin County Jail without bond.
At an 11 a.m. news conference, Sheriff William Snyder said investigators flew to North Carolina, where Williams lived, and brought him back to Martin County.
Snyder said Williams confessed to killing her and disposing the body in a wooded area of Martin County near Jonathan Dickinson State Park.
Crews on Wednesday are searching a 15-mile area for her body.
Williams was taken into custody at about 8:30 p.m. Tuesday.
Officials said Todd died the night of her disappearance, however her body has not been found.
"These two people were divorced. There were known issues about money," Sheriff William Snyder said.
However, Snyder said he was reluctant to discuss a possible motive because he didn't want to prejudice the case for a jury.
Snyder said Todd's young child, who is under the age of 3, was nearby when she was killed.
Williams told investigators that no accomplices helped him kill his ex-wife or dispose of her body.
Tricia Todd went missing in late April
Todd was last seen at a Publix on Bridge Road in Martin County on April 27.
Her disappearance prompted a large-scale search by area police agencies and volunteers that included cadaver dogs.
On May 3, the sheriff's office said Williams willingly submitted to a polygraph exam and nothing he said pointed to any links to her disappearance.
Earlier this month Williams was interviewed in North Carolina by a lieutenant, two detectives and an assistant state attorney.
The Air Force said in a written statement Wednesday they are "cooperating fully with civil authorities in this case."
Before his arrest, Williams was assigned as a field training detachment instructor with the 372nd Training Squadron.
A representative for the family of Tricia Todd has released this statement:
