SKOWHEGAN — One year ago, Luc Tieman, an Army veteran from Fairfield, went before a judge in Somerset County Superior Court to plead not guilty to a charge of knowing or intentional murder in the death of his wife, Valerie Tieman.

The killing is alleged to have happened the previous August. Authorities charge that Tieman buried her body in his parents’ backyard and that he later concocted contradictory stories about what happened.

Tieman, 34, remains held without bail at the Somerset County Jail in East Madison as he awaits an evidence-suppression hearing scheduled for Dec. 4.

His murder trial is scheduled for jury selection March 29, with the trial to follow on April 2.

Tieman, who might be suffering from post-traumatic stress disorder from a mortar explosion in combat, was indicted by a Somerset County grand jury on a charge of murder in connection with the death of his wife, who was 34.

Valerie Tieman was reported missing Sept. 9, 2016, by her parents, who live in South Carolina, after they had not heard from her for more than two weeks.

The murder is alleged to have taken place Aug. 25 – 15 days before her parents reported her missing and five days before Tieman claimed his wife disappeared from the Walmart parking lot in Skowhegan. He did not report her missing.

Tieman initially told police that she disappeared from his pickup truck outside Walmart in Skowhegan but later said she died of a drug overdose.

An autopsy report from the State Medical Examiner’s Office says Valerie Tieman died from two gunshot wounds to the head and was found buried in Luc Tieman’s parents’ backyard off Norridgewock Road in Fairfield.

According to court records, Luc Tieman’s defense attorney, Stephen Smith, filed a motion to suppress as evidence statements Tieman is alleged to have made to state police detectives in September 2016.

Smith says in the motion that Tieman was actually in police custody without the benefit of having been read his right to remain silent under the Miranda rules.

According to a court affidavit filed by Detective Hugh Landry and cited in Smith’s motion to suppress: “Luc initially denied any knowledge of the body, then changed his statement,” saying that Valerie had a drug addiction and that he witnessed her overdose and die.

“Luc said he brought home heroin for Valerie and loaded a needle for her. She took the needle and injected herself. Luc said Valerie smiled at him and then stopped breathing. Luc stated he left her in bed until late at night and then took her outside and dug a trench and buried her.”

Smith contends that Luc Tieman made the statements to multiple police officers in what “a reasonable person” would perceive to constitute police custody.

According to the autopsy report, Valerie Tieman’s cause of death was “gunshot wounds of head and neck,” and she was “shot by other person(s),” meaning it was not a suicide.

When her body was found, it was “clad in damp clothing consisting of brown boots, bright yellow/green socks, a grey T-shirt, blue jeans and a navy shirt,” according to the report dated Oct. 5. It was signed by Clare Bryce, a medical doctor and deputy chief medical examiner who performed the autopsy Sept. 21, the day after Tieman’s body was found.

Beneath the body were a bag of potato chips, a bottle of perfume and a note that “reportedly has an apologetic tone,” according to investigators.

In interviews with the Morning Sentinel, Luc Tieman’s friends said he had been unfaithful to his wife and sought companionship with other women, telling them his marriage was ending around the time she disappeared.
