SKOWHEGAN, Maine (AP) — Jury selection is expected later this week in the trial of a Maine man charged with killing his wife and burying her in a shallow grave behind his parents' home.

Luc Tieman, who's pleaded not guilty to murder, told police that he watched his wife overdose in 2016.

An autopsy showed that Valerie Tieman had ingested opioids, but died from gunshots to the head and neck.

The South Carolina native was buried along with a bag of potato chips, a bottle of perfume and a note that took "an apologetic tone."

Jury selection is scheduled to begin on Thursday in Superior Court in Skowhegan. If a jury is seated, then the trial will begin on Monday.
