More than a year after Martin County nurse and U.S. Air Force veteran Tricia Todd was murdered and her killer was sentenced, her story is being told again on TV for millions to see.

Oxygen’s "Criminal Confessions" will retell in detail the murder of Todd through interviews with investigators from the Martin County Sheriff’s Office, prosecutors from the state attorney’s office and members of her family, as well as through case-file records from the month-long investigation. Family and investigators share their frustrations with the case and how sometimes it "felt like we were in a movie" as pieces of the crime unraveled. The two-hour special is set to air at 7 p.m. Sunday.

"That month, that’s all we lived, breathed, was Tricia Todd. It was our duty to bring her home," Detective Sgt. Yesenia Carde said in the show. "The confession definitely was key and we were able to bring justice to her family."

"Criminal Confessions" is a new true-crime series by "Law and Order" producer Dick Wolf that digs into the sometimes tense and telling interrogation rooms where those suspected of the crime eventually confess. In the Todd episode, the show takes viewers down the ever-suspicious road of her ex-husband, Steven Williams, who eventually confesses to her death, takes a 35-year plea deal and leads investigator to Todd’s body, which he had dismembered and buried in a secluded area of a nature preserve in Martin County.

Sheriff William Snyder told The Palm Beach Post the case did claim the national spotlight as it was going on, so he wasn’t surprised when the show’s producers came to the department, but that going through the process made him appreciate what his deputies do every day on the job.

"When I was interviewed, it was a reminder of just how profoundly difficult and challenging law enforcement can be," he said. "And how a day can change so dramatically."

On April 26, 2016, family members of the 30-year-old Todd called authorities, saying the mother did not pick up her daughter, Faith, from her babysitter. For days, the Hobe Sound community came together with authorities to search the area. During that time, Williams was interviewed several times and maintained a story that checked out time and time again. As authorities continued to rule out other suspects and reasons for her disappearance, Williams kept popping up as someone to look into.

Detective Daniel Dulac said in the show the team was happy to bring closure to the family because there were "several moments where we thought this would never be solved."

Though investigators had their "aha moment" when they found several videos of a man walking along Dixie Highway from Todd’s house to where Williams was staying while he visited his daughter, they knew the video alone would not hold up in court and that they needed a confession.

Snyder told The Post the work of his detectives to get everything done within a month’s time "was nothing short of miraculous."

"I’ve been in this industry going on 45 years and I don’t know I’ve ever seen a case that was so far out from being solved," he said. "I stood back in awe of my detectives."

Williams initially said Todd’s death was an accident and that he got rid of her body because he didn’t want to be blamed for her death. He was arrested May 26 and soon after made a 35-year plea deal for second degree murder in exchange for bringing authorities to Todd’s body. But investigators knew as soon as he led them to the plastic tub filled with acid in which he’d buried her body parts at the Hungryland Wildlife and Environmental Area, along the border of Palm Beach and Martin counties, that they were dealing with a premeditated murder.

Snyder told The Post that without the confession, they may have never gotten a body and he commends the investigators for their interviewing skills that eventually got Williams to crack.

"They are the ones who have to control their own emotions and visceral disgust with the suspect," he said. "But to (interview) a man like (Williams) — who I consider pretty cunning and crafty and worthy of the chess match of an interview — and for them to come out on top was incredible."

After Williams was sentenced, he told detectives he killed Todd because he was upset he didn’t get to see his daughter as much as he wanted, there were financial issues between him and Todd and that he was upset that Todd continually "disrespected him" after their divorce.

While the show delves into much that was covered during the days of Todd’s disappearance and the months between that time and Williams’ sentencing, there are new details that emerge. Just before his confession, Williams told Todd’s family he planned to take his daughter with him back to North Carolina. Investigators said that caused them to go into "hyper-drive" to get a confession.

Williams’s girlfriend was also interviewed and stood by him, saying he would never do anything to hurt Todd. But after investigators told her how Williams was accused of killing several of Todd’s animals through the years, she said one of her dogs also died suddenly. Detectives brought her into an interview room with Williams in the hope she could get a confession out of him, but that didn’t work.

As for Faith, family members said she was adopted by Todd’s brother, Jonathan, and is being raised with her two cousins. Sheriff’s office detectives said they still check in on the little girl to make sure she’s doing OK.

Investigators also still hope that the Air Force will convict Williams for the murder after he finishes his prison sentence. The sheriff’s office confirmed because Williams was an employee of the U.S. Air Force at the time of the murder, they can charge him with murder in military court, where there is the possibility of the death penalty.

Assistant State Attorney Tom Bakkedahl said he knew he made a "deal with the devil," when he took the 35-year plea, but knows there is still hope for Williams to go away for a longer time.

"If we’re going to get full justice, this guy can never walk free again," Bakkedahl said in the show.
