JACKSON COUNTY — A 23-year-old Carbondale woman has pleaded guilty to the murder of a former Salem woman over the summer.

Lauren Stinde pleaded guilty today in the first-degree murder of Robin Stief of Mt. Vernon, and formerly of Salem back in August.

Jackson County State’s Attorney Michael Carr says a sentencing hearing for Stinde has been set for Feb. 1 at 10:30 a.m.

Carr says the charge carries a sentencing range of not less than 20 years and not more than 60 years in prison.

Stief’s burned remains were found in a wooded area in the 900 block of East Main Street in Carbondale on Aug. 30. According to a Carbondale Police investigation, Stief had recently associated with Stinde.

Police arrested Stinde for her involvement in the concealment of Stief’s remains on Oct. 28. After she was arrested, Stinde confessed to detectives about her role in the murder and her role in the concealment of Stief’s body.

Carr also announced Monday that first degree murder charges were filed against Tiesha D. Anderson and Robert J. Dennis. They each face two counts of first degree murder and one count of concealment of a homicidal death.

This case is still under investigation by Carbondale Police along with Illinois State Police Crime Scene Services.
