A young woman is discovered dead in her burning home. She had been romantically involved with a firefighter—could he have started the fire to conceal her murder?

Oregon woman Susan Lane-Fournier, 61, was found dead after going missing on a hike with her two dogs.

Her estranged husband, Michel Fournier, 71, was arrested for murder.

Lane-Fournier was reported missing on Nov. 22, and her body was discovered on Nov. 30. The dogs found with her were confirmed to be hers.

Lane-Fournier had filed for divorce two weeks before she disappeared.

An autopsy ruled her death as a homicide.

Coworkers mentioned she feared for her life before her disappearance.

Detectives are seeking information about Michel Fournier's activities leading up to the incident.

Melissa Lamesch, a devoted EMT, was due to give birth to a baby boy in two days when Matthew Plote, the father, set her house on fire, resulting in her death.

Plote, a firefighter-paramedic, was found guilty of murder and arson after a trial where evidence suggested he strangled Melissa.

The investigation revealed Plote's motive, lack of denial, and suspect behavior.

The prosecution's case was supported by expert testimonies, while the defense presented an alternative theory.

Plote was sentenced to life in prison, providing some closure for the Lamesch family, though nothing can bring back Melissa or her unborn child, Barrett.
