Suspect In McCook County Stand-Off Has Surrendered To Law Enforcement

MONTROSE, S.D. -A Montrose man is in custody after a McCook County deputy was shot in the arm early Wednesday morning.

The suspect has been identified as 37-year-old Matthew Rumbolz.

It took 4 hours for law enforcement to get Rumbolz to surrender this afternoon, but it took even longer to locate him. The incident started in McCook County when a deputy was in pursuit of Rumbolz for a traffic violation.
That pursuit went into Lake County where officials say Rumbolz went into a ditch near the intersection of 453 and 243 St. and that’s when shots were fired.

The McCook deputy was shot in the arm but has already been released from the Madison hospital and is in good condition.

Rumbolz was found in a ditch armed with a shotgun around 10 a.m. and he surrendered to law enforcement at 3:45 p.m.

“There was a period of time there where communication had stopped. Attempts were made to reaccess communication again which was very successful again over the course of the 3 to 4 hour time frame,” said Lake County Sheriff  Tim Walburg.

Officers have not released if any drugs were located in Rumbolz car or if alcohol played a factor.

The name of the deputy as well as what charges Rumbolz is facing have not been released either.

Multiple agencies are working on this case including DCI, McCook County, Lake County, Brookings County and the Minnehaha County Sheriff’s Office.
