- Location: Manistee National Forest, Newaygo County, Michigan
- Perpetrators: Paul Michael Jones & Matthew Wayne Jones (Brothers; Convicted 2015)
- Investigating Agency: Newaygo County Cold Case Task Force & Michigan State Police

On the warm summer night of July 17, 1989, eighteen-year-old high school graduate Shannon Siders was socializing with friends at a party spot known as ‘the woods’ in the Manistee National Forest near Newaygo, Michigan. She never returned home. Three months later, a hunter discovered her partially clothed, decomposed body hidden in a secluded clearing off a dirt two-track road. She had suffered massive blunt force head trauma. For over two decades, the Shannon Siders murder cast a dark shadow over the rural community. In 2011, a tenacious multi-agency cold case task force re-interviewed dozens of witnesses, uncovering critical physical timelines and admissions that led to the 2014 arrests and 2015 convictions of brothers Paul and Matthew Jones.
The Summer Party & The Two-Track Forest Discovery
Shannon Siders had graduated from high school in June 1989 and was planning to enlist in the United States Navy. On the evening of July 17, 1989, she rode in a vehicle with several local youths, making stops at party spots in the Manistee National Forest. Witnesses reported seeing Siders riding in a vehicle with brothers Paul Jones (then 21) and Matthew Jones (then 18) in the early morning hours of July 18.
On October 15, 1989, a deer hunter walking through the Manistee National Forest in Brooks Township discovered human skeletal remains. Michigan State Police detectives and Newaygo County Sheriff’s investigators processed the scene. Forensic pathologists determined Siders died from massive blunt impact trauma to her skull. While environmental exposure had degraded direct biological fluids, clothing items and physical trajectory evidence were meticulously preserved in evidence storage.
Twenty-Two Years of Silence & Community Impasse
During the initial 1989 investigation, investigators interviewed hundreds of local residents. Rumors and contradictory alibis circulated throughout Newaygo County, but witnesses remained reluctant to cooperate due to intimidation and fear of retribution from local criminal figures. The investigation gradually stalled into cold case status.
Shannon’s father, Bob Siders, refused to let the case be forgotten, maintaining regular contact with state police commanders and advocating for renewed resources.

The 2011 Cold Case Task Force Breakthrough
In December 2011, Newaygo County Sheriff Pat Hedlund and Michigan State Police established a dedicated Cold Case Task Force headed by MSP Detective Sergeant Todd Goodrich. The task force reviewed every single page of the 2,500-page case file, re-interviewing over 400 individuals across seven states.
Task force detectives utilized modern forensic interview techniques to break down decades of silence. Key witnesses came forward with corroborating testimonies: individuals who had heard Paul and Matthew Jones make detailed, non-public admissions about taking Shannon to the woods, sexually assaulting her, and beating her to death when she fought back. Crucially, cell phone location modeling and vehicle trajectory reconstruction dismantled the brothers’ historical alibis.
Arrests, Courtroom Convictions & Justice in Newaygo
In June 2014, the Michigan Attorney General’s Office arrested Paul Michael Jones and Matthew Wayne Jones, charging them with first-degree open murder. In May 2015, following a highly publicized four-week trial featuring testimony from dozens of witnesses and forensic experts, separate Newaygo County juries found both brothers guilty.
Matthew Jones was sentenced to life imprisonment without the possibility of parole, and Paul Jones was sentenced to 30 to 50 years in state prison. The successful prosecution was hailed as a benchmark model for how multi-agency cold case task forces can resolve complex rural homicides through exhaustive witness re-engagement.

The Manistee National Forest Crime Scene & Cold Case Review
On July 18, 1989, eighteen-year-old Shannon Siders vanished after attending a social gathering with teenagers in Newaygo, Michigan. Three months later, on October 15, 1989, a deer hunter walking through a remote section of the Manistee National Forest in Brooks Township discovered her skeletal remains. Autopsy results established that she died from blunt force craniocerebral trauma.
For over two decades, the investigation remained stalled due to conflicting witness statements and the lack of biological DNA from the wilderness scene. In 2011, the Michigan State Police, Newaygo County Sheriff’s Office, and the Michigan Attorney General’s Office established the Shannon Siders Cold Case Task Force, systematically re-interviewing more than 400 individuals who had attended the 1989 gatherings.
Grand Jury Proceedings & The Jones Brothers Indictment
In 2014, a Newaygo County multi-county grand jury convened to review newly gathered witness testimony and circumstantial physical evidence. The grand jury heard testimony that brothers Matthew and Paul Jones were the last individuals seen with Siders in Paul’s vehicle at a local party spot known as ‘the hole’ in the Manistee National Forest.
Witnesses who had remained silent for 25 years out of fear came forward with detailed accounts of the brothers’ admissions and threatening behavior following the disappearance. In June 2014, Michigan State Police arrested 44-year-old Matthew Jones and 42-year-old Paul Jones, charging both with first-degree premeditated murder.
Dual-Jury Trial & Michigan State Police Cold Case Legacy
In May 2015, a landmark trial featuring two separate juries simultaneously hearing evidence against Matthew and Paul Jones commenced in Newaygo County Circuit Court. Prosecutors presented compelling testimony showing consciousness of guilt, timeline inconsistencies, and corroborated admissions. Matthew Jones was convicted of first-degree murder and sentenced to life without parole, while Paul Jones was convicted of second-degree murder and sentenced to 30 to 75 years.
The Shannon Siders case stands as a powerful demonstration that relentless investigative persistence, cold case grand juries, and renewed witness cooperation can secure justice in decades-old homicides even in the absence of recoverable DNA profiles.
Newaygo County Multi-County Grand Jury Strategy & Cold Case Dynamics
The breakthrough in the Shannon Siders homicide investigation was made possible by the strategic utilization of Michigan’s multi-county grand jury system. Because three decades of community silence had prevented traditional witness cooperation, prosecutors used subpoena powers to compel testimony under oath from dozens of individuals who attended the 1989 forest gatherings.
This legal mechanism allowed the Michigan Attorney General’s Cold Case Unit to overcome witness intimidation, systematically dismantling false alibis and establishing a coherent physical and circumstantial timeline that secured convictions against both Matthew and Paul Jones.
Forensic Pathology & Craniocerebral Biomechanics
During the 2015 trial proceedings, forensic pathologists and biomechanical engineers testified regarding the specific impact trauma documented on Shannon Siders’s skull. The physical fractures were consistent with repetitive blunt force delivered by a heavy tool or tire iron, directly corroborating witness statements regarding physical weapons observed in the defendants’ vehicle.
The dual-jury trial format utilized in Newaygo County Circuit Court prevented evidentiary prejudice while allowing prosecutors to present identical forensic testimony, establishing a legal precedent for multi-defendant cold case prosecutions in Michigan.
