The primary suspect in a murder investigation out of Tomah is in custody, following a dramatic high speed chase along the interstate.

Twenty-four-year-old David Cummins is being held in Rock County for eluding an officer, operating while intoxicated, and carrying a concealed weapon.

Authorities had been looking for him since Friday night. That's when officers were dispatched to a home for Fort McCoy employees, located in Tomah.

Upon arrival, police found 50-year-old John Cummins bleeding from the head. He was pronounced dead at an area hospital.

Just before ten Saturday night, state troopers were alerted of a possible drunken driver traveling north on I–90 near Beloit. Authorities recognized the vehicle as being wanted in connection with the Tomah murder investigation. Its driver – who was reported as being "armed and dangerous" – led troopers on a chase, reaching speeds of more than 100 miles per hour.

The vehicle was finally stopped near the Stoughton exit in Dane County, after driving over road spikes. David Cummins was taken into custody at gun point without further incident.

Anyone with information on the Tomah murder is asked to call Monroe County Crime Stoppers at (608) 372-STOP or Monroe County Central Dispatch at (608) 372-8090.
