WITOKA, Minn. – Deputies traced the ping of a 911 emergency hang-up call to farmland east of Witoka in search of perhaps an injured person. This was about 12:30 a.m. A heat-seeking drone detected nothing. The foot search began off County Road12 on Reinhard Drive, then expanded to the Blackberry Road area. Deputies found a UTV by itself but nothing appeared amiss. They knocked on farmhouse doors about any problems or anyone missing — to no avail.
