A new report from Michigan State Police shows a majority of violent crimes are not solved.
Statistics show there were more than 131,000 violent crimes in 2015, including murder, kidnapping, rape, assault and human trafficking.
Only 37-percent of those crimes were solved.
Howeve, the "solve" rate has gone up over the past ten years.
State Police say the Secure Cities Partnership, which has troopers working with local police investigators, has helped reduce violent crime.
