MINNEAPOLIS – New details have been released about what led Minneapolis police to an arrest in a nearly 40-year-old murder case in Hennepin County.

Matthew Brown, 66, is now charged with second-degree murder for a crime that dates back to 1984. Police say Brown killed Robert Miller 39 years ago this week.

Newly-obtained court documents show what led to Brown's arrest. State investigators developed a DNA profile for the suspect in 2018 and consulted with a genealogist.
